Dipeptidyl-dipeptidase
Dipeptidyl-dipeptidase (, dipeptidyl tetrapeptide hydrolase, dipeptidyl ligase, tetrapeptide dipeptidase) is an enzyme. This enzyme catalyses the following chemical reaction
Preferential release of dipeptides from a tetrapeptide, e.g. Ala-Gly!Ala-Gly. Acts more slowly on Ala-Ala!Ala-Ala and Gly-Gly!Gly-GlyThis thiol-activated peptidase is isolated from cabbage ( Brassica oleracea).
