WebbpH Each enzyme has an optimal pH. A change in pH can alter the ionization of the R groups of the amino acids. When the charges on the amino acids change, hydrogen bonding within the protein molecule change and the molecule changes shape. The new shape may not be effective. The diagram below shows that pepsin functions best in an acid environment. WebbProteases, secreted from Bacillus sp., typically have molecular weights ranging from 20,000 to 30,000. They are typically stabilized by Ca 2+ and have high isoelectric points. It is highly soluble in detergents at a wide range of pH and temperatures. Protease improves healing process by efficiently removing necrotic materials from wounds.
