3. pH. The pH must be correct for each enzyme to work at its best. Different enzymes work best at different pH values. The optimum pH for an enzyme depends on its site of action. For example, enzymes in the stomach have an optimum pH of about 2 because the stomach is acidic, but intestinal enzymes have an optimum pH of about 7.5.

Enzymes / ˈ ɛ n z aɪ m z / are macromolecular biological catalysts.Enzymes accelerate chemical reactions.The molecules upon which enzymes may act are called substrates and the enzyme converts the substrates into different molecules known as products.Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life.

Methods: In the absence of enzymes, the rate of a reaction can be thought to increase linearly with substrate concentration. The reaction rate is given as dp/dt, or the change in product over time: where S is the substrate concentration, and k is the frequency at which substrate is converted to product.

Apr 28, 2017 · A coenzyme is an organic non-protein compound that binds with an enzyme to catalyze a reaction. Coenzymes are often broadly called cofactors, but they are chemically different.
"Some of our enzymes are even more efficient than the current processes because you avoid all the stages that are required to process the microbial products: fermentation, purification, and cold.

"Highly characterized for more consistent performance, Proteinase K is a subtilisin-related serine protease that will hydrolyze a variety of peptide bonds. Proteinase K is active in a wide range of temperatures and buffers with optimal activity between 20 and 60°C and a pH between 7.5 and 12.0. Activity is stimulated when up to 2% SDS or up to 4 M urea are included in the reaction.
Biochemistry. In biochemistry, the substrate is a molecule upon which an enzyme acts. Enzymes catalyze chemical reactions involving the substrate(s). In the case of a single substrate, the substrate bonds with the enzyme active site, and an enzyme-substrate complex is formed. The substrate is transformed into one or more products, which are then released from the active site.
