The conversion of porcine insulin to human insulin is catalyzed by trypsin which replaces C-terminal alanine (β30) residue by a threonine. Thermolysin is used to produce aspartame from aspartic acid. Aspartate is produced from aspargine by using asparginase. Plasminogen is converted to plasmin by streptokinase enzyme.
