WebbEizo Takahashi, Keinosuke Okamoto, in Handbook of Proteolytic Enzymes (Third Edition), 2013. Activity and Specificity. ASP is an endopeptidase and is defined as a member of the kexin subfamily of serine proteases [15,16]. Its optical pH is 7.5 and its activity is lost by heating at 60°C for 10 min, indicating that ASP is heat-labile [17]. 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. pureed tofu
