WebJan 11, 2016 · Protease enzymes, which catalyze cleavage of proteins, are essential enzymes for biotechnology. Engineering of natural proteases to change their site of cleavage is an exciting prospect, but this process usually leads to relaxed substrate selectivity, rather than a true change in enzyme specificity. WebSome enzymes even distinguish between D- and L-stereoisomers, binding one stereoisomer but not the other. Urease, for example, is an enzyme that catalyzes the hydrolysis of a single substrate—urea—but not the closely related compounds methyl urea, thiourea, or biuret. The enzyme carboxypeptidase, on the other hand, is far less specific.
