A Systems Approach to advanced enzyme technology
2Background History of enzymes
Alcoholic fermentation oldest known enzyme
reaction Y G A CO2
- Phenomena believed to be spontaneous reactions
until 1857, when the French
chemist Louis Pasteur proved that fermentation
occurs only in the presence of living cells. - Subsequently the German chemist Eduard Buchner
discovered (1897) that a cell-free
extract of yeast can cause alcoholic
fermentation. - The ancient puzzle was then solved the yeast
cell produces the enzyme and
the enzyme brings about the fermentation - As early as 1783 the Italian biologist Lazzaro
Spallanzani had observed that meat could be
digested by gastric juices extracted from hawks.
3Background History of enzymes
- Probably first experiment in which a vital
reaction was performed outside the living
organism - After Buchner's discovery scientists assumed that
fermentations and vital reactions in general were
caused by enzymes - Nevertheless, all attempts to isolate and
identify their chemical nature were unsuccessful - In 1926 the American biochemist James B. Sumner
succeeded in isolating and crystallizing urease.
4Background History of enzymes
- Four years later pepsin and trypsin were isolated
and crystallized by American biochemist John H.
Northrop - Enzymes were found to be proteins, and Northrop
proved that the protein was actually the enzyme
and not simply a carrier for another compound - Research in enzyme chemistry in recent years has
shed new light on some of the most basic
functions of life - Ribonuclease, a simple three-dimensional enzyme
discovered in 1938 by American
bacteriologist René Dubos. - Isolated in 1946 by American chemist Moses unitz
- Synthesized by American researchers in 1969
5RIBONUCLEASE ENZYME
6Background History of enzymes
- The synthesis hooks 124 molecules in a specific
sequence to form the macromolecule - Led to identification of those molecular areas
that carry out its chemical functions - Opened up the possibility of creating specialized
enzymes with new properties - This potential has been greatly expanded in
recent years by genetic engineering techniques
that have made it possible to produce some
enzymes in great quantity

9Industry drawbacks
- Non-specific reactions may result in poor product
yields. - High temperatures and/or pressures needed to
drive reactions lead to high energy costs. May
require large volumes of cooling water
downstream. - Harsh and hazardous processes involving high
temperatures, pressures, acidity or alkalinity
need high capital investment, and specially
designed equipment and control systems. - Unwanted by-products may prove difficult or
costly to dispose of. - High chemical and energy consumption, and harmful
by-products have a negative impact on the
environment.
10Drawbacks eliminated by enzymes
- Reactions carried out under mild conditions
- Highly specific
- Involve very fast reaction rates
- Reactions are carried out by numerous enzymes
with different roles. - Industrial enzymes originate from biological
systems which contribute to sustainable
development through being isolated from
microorganisms which are fermented using
primarily renewable resources. - Small amounts of enzymes are required to carry
out chemical reactions - Reaquires little storage space.
- uncomplicated and widely available equipment can
be used - Reactions are easily controlled and can be
stopped when the desired degree of substrate
conversion has been achieved. - Reduce the impact of collateral damage on the
environment by reducing the consumption of
chemicals and energy, and the subsequent
generation of waste. - Developments in genetic and protein engineering
have led to improvements in the stability,
economy, specificity and overall application
potential of industrial enzymes.
11What are enzymes?
An enzyme is a protein which acts as a specific
biological catalyst facilitating a given reaction
by lowering the amount of required energy.
To date, scientists have identified over 1,500
different enzymes.
12What are enzymes?
- Six main classes by type of reaction catalyzed
- Classes are split into groups and subclasses
- Ex., lactase catalyzes the conversion of milk /
sugar to galactose and glucose - Lactase has the systematic name
beta-D-galactoside galactohydrolase, and the
classification number EC 3.2.1.23.
13SIX MAIN ENZYME CLASSES
14What are enzymes?
- Globular, water soluble proteins, (few
exceptions)
- Allows / facilitates chemical reactions to occur
such as those that release nutrients from feed
during digestion
- Without the enzyme catalyst the reaction would
either not take place or would happen very slowly
- If a reaction is favorable ( ?G lt 0), the
activation energy E(act) determines how fast it
will go.
15What are enzymes?
- Though an enzymatic catalyst takes part in the
chemical reaction it remains unchanged and is
available to repeat the task
16What are the most important enzymes to our
industry?
- Virtually all enzymes employed in the feed
industry are hydrolases.
- Some enzymes that are of practical value to the
livestock industry
- Xylanases, amylases, phytases, proteases,
cellulases, betaglucanases, and pentosanases,
are available for use in diet formulations.
- These enzymes can be mixed and matched to form
an enzyme cocktail to fit any particular diet
need.
17Why are enzymes needed in feed formulations?
Trials confirm that enzyme supplementation
results in improved animal performance.
- Young animals lack many endogenous enzymes or
sufficient quantities thereoff.
- Sick animals may have a damaged intestinal
lumen resulting in limited nutrient absorption.
- Animals under stress or at a high level of
production may have an impaired digestive system.
18Why are enzymes needed in feed formulations?
Problems in feed ingredients
- Raw materials may contain anti-nutritive
factors. Ex. pentosans or betaglucans present in
wheat or barley.
- Addition of appropriate enzyme aids digestion
of the material improving feed value.
- Increasing environmental awareness and
restrictions on pollutants and contaminants
confirm the value of enzymes in the breakdown of
such materials. Ex Phytase/ phosphorus
19How do enzymes work?
Specificity
- Specific enzymes may be incorporated into
specific diets in order to solve specific
problems
20How do enzymes work?
- Enzyme catalyzed reactions are often from 100
million to more than 10 billion times faster than
the same reaction in the absence of the enzyme.
- Most enzymes catalyze the transfer of
electrons, atoms or functional groups.
21Factors influencing enzyme activity
- Optimum pH
- Optimum Temperature
22Factors influencing enzyme activity
- Optimum Enzyme concentration
- Optimum Substrate concentration
23Factors influencing enzyme activity
24Factors influencing enzyme activity
A competitive inhibitor
A non-competitive inhibitor molecule
25Factors influencing enzyme activity
26Factors influencing enzyme activity
- Optimum pH pH at which enzymes operate best.
Activity decreases on either side of pH optimum.
27Factors influencing enzyme activity
- Optimum Temperature
- Within a given range, for every 10 degrees the
temperature increases, enzyme activity doubles. - Enzymes become denatured at elevated
temperatures. - Enzymes have an optimum temperature which varies
according to - Enzyme source.
- Salt levels in the medium to which the enzyme is
added. (For example, amylases from animal
sources are less heat stable than those from
fungal sources (Aspergillus) which are in turn
less stable than bacterial amylases (Bacillus). - Mineral Content Certain minerals stabilize
enzymes while others cause inactivation. Calcium
and magnesium are essential for good starch
breakdown (amylases) and increase enzyme
stability to temperature. Heavy metals such as
iron are typically detrimental to enzymes, and
may in some cases be used to inactivate or stop
enzyme reactions.
28Enzyme concentration
- Normally enzymes are present in cells in low
concentrations. - As enzyme concentration increases the rate of the
reaction increases linearly, because there are
more enzyme molecules available to catalyse the
reaction. - At very high enzyme concentration the substrate
concentration may become rate-limiting, so the
rate stops increasing.
29Substrate concentration
- As the substrate concentration increases, the
rate increases because more substrate molecules
can collide with enzyme molecules, so more
reactions will take place. - As substrate concentration gets higher the enzyme
molecules become saturated so there are few free
enzyme molecules. Adding more substrate doesn't
make much difference (though it will increase the
rate of E-S collisions). - The maximum rate at infinite substrate
concentration is called vmax, - The substrate concentration that gives a rate of
half the maximum rate vmax is called KM. - The vmax and KM values are useful for
characterising an enzyme. - A good enzyme has a high vmax and a low KM.Â
30Substrate concentration
31Covalent modification
- Activity of some enzymes is controlled by others.
- These enzymes modify the protein chain by cutting
it, or adding a phosphate or methyl group. - Turns inactive enzyme into active (or vice
versa). - Used to control many metabolic enzymes and to
switch on enzymes in the gut e.g. hydrochloric
acid in stomach activates pepsin activates
rennin.
32Inhibitors
- Inhibitors inhibit the activity of enzymes,
reducing the rate of their reactions. - Found naturally, but are also used artificially
as drugs, pesticides and research tools.
33Inhibitors
- There are two kinds of enzymatic inhibitors.
Non-competitive
Competitive
34Competitive Inhibitors
- Molecule has similar structure to normal
substrate molecule. Fits into active site of the
enzyme. - Competes with substrate for the active site, so
reaction is slower. - Increase KM for enzyme, but no effect on vmax.
- The rate can approach a normality if substrate
concentration is increased sufficiently. - The sulphonamide anti-bacterial drugs are
examples of competitive inhibitors.
35Non-competitive inhibitors
- Inhibitor molecule is different in structure than
the substrate molecule - Will not fit into active site.
- Binds to another part of the enzyme molecule.
- Change enzyme and active site shape so it no
longer binds substrate molecules. Result is
reduction of active enzyme numbers (just like
decreasing the enzyme concentration). Therefore
decrease vmax, but have no effect on KM. - Reversible inhibitors - bind weakly and can be
washed out. - Irreversible inhibitors - bind tightly and cannot
be washed out. - Poisons like cyanide, heavy metal ions and some
insecticides are all examples of non-competitive
inhibitors.
36RATE EQUATION FOR PRODUCT INHIBITION
37Allosteric Effectors
- Activity of some enzymes is controlled by
certain molecules binding to a specific
regulatory or allosteric site on the enzyme.
- Allosteric site is distinct from the active site
- Different molecules can inhibit or activate the
enzyme, allowing sophisticated control of the
reaction rate - Few enzymes can do this. They are often at the
start of long biochemical pathways - Generally activated by the substrate of the
pathway and inhibited by the product of the
pathway, thus only turning the pathway on when it
is needed
38Allosteric Effectors
39Economic benefits
- Increases daily weight gain
- Increases egg production
- Lowers feed conversion
- More uniform weights / increased nutrient
absorption - Lower incidence of digestive problems caused by
unassimilated fiber which also improves litter
quality - Reduces fecal volume and nitrogen excretion
levels - Cleaner eggs and better egg yolk color
- Use of lower cost ingredients
- Maintains and improves performance levels
- Increases ratio of lean to fat tissue
- Can "inactivate" mycotoxins in feeds
40What is Dinazyme?
Several types of enzyme technologies are offered
as Dinazyme
- Dinazyme B/W Dry and Liquid
- Dinazyme C/S PBM Dry and Liquid
- Dinazyme PSE, (Phytase) Dry
41What is Dinazyme C/S PMB
- Supplement for corn soy based poultry and pig
diets containing high glucan barley levels.
42What is Dinazyme C/S PMB
- A diet supplement which enhances nitrogen
utilization and increases protein digestibility
with the active ingredient protease, resulting in
increased absorption of amino acids and peptides.
- DINAZYME C/S also contains amylase-breaks down
starch content and Xylanase, a complex hydrolytic
enzyme preparation which has an effect on
hemicellulose substrates containing xylan, manan
and glucan. - A combination of amylase, Xylanase and protease
boosts the digestibility of typical corn and
soybean meal-based diets, resulting in more
nutrients available for growth. - Inclusion of DINAZYME C/S in diet supplements
provides endogenous enzymes animals lack or
produce in low amounts.Â
43WHAT MAKES DINAZYME MORE EFFECTIVE THAN OTHER
ENZYMECOMBINATIONS
- Effective action due to presence of other
important hydrolytic enzymes, which decompose
cellulose, lichenin, araban and pectin. - Dinatec makes use of important technical concepts
such as - Covalence modification,
- The use of specific allosteric substances and
enzyme co-factors that are conducive to higher
enzymatic efficacy - Enzyme concentration
44What can Dinazyme C/S PMB do for you?
- Contents / effects
- Protease, enhanced nitrogen utilization and
increased protein digestibility - Amylase, increased digestibility of starch in
pig and poultry diets - Betaglucanase, reduced digesta viscosity in
poultry diets decreases anti- nutritional
effects of NSP reduces soluble NSP in disgesta.
- Pectinase, more complete hydrolysis (digestion)
of pectins in wheat and corn based diets
- Xylanase reduces digesta viscosity decreases
anti-nutritional effects of NSP reduces soluble
NSP in digesta hence increased absorption of
amino acids and peptides.
Non Starch Polysaccharide
45Why should you use Dinazyme?
High energy diets high on starch and protein
content are desirable at an early age for the
monogastric.
Young animal's endogenous enzyme system not
fully developed. Unable to adapt quickly enough
for demands of current feed management programs.
Immature pancreas needs time to adapt to new diet
and produce necessary amounts and types of
digestive enzymes.
Result - Undigested feed is wasted.
Undigested feed promotes "nutritional scours" and
provides substrate for the growth of
diarrhea-causing pathogens.
46Why should you use Dinazyme?
- The Solution Dinazyme C/S-PMB
- To supplement the immature endogenous enzyme
system.
- To maximize performance, even with limited
digestive capacity, e.g. case of young animals
or rapid diet changes.
- To optimize nutrient utilization of high energy
feedstuffs.
- To enable use of normally undigestible alternate
lower cost ingredients
47ECONOMICS
Data suggest that an average improvement in
nutrient utilization of 3 5 can be obtained
Leeson and Summers (1976) reported that high
moisture content corn harvest necessitated high
temperature drying time retention conditions,
reduced ME value of corn by as much as 3
compared to the expected value.
