Membrane dipeptidase (EC 3.4.13.19, renal dipeptidase, dehydropeptidase I (DPH I), dipeptidase, aminodipeptidase, dipeptide hydrolase, dipeptidyl hydrolase, nonspecific dipeptidase, glycosyl-phosphatidylinositol-anchored renal dipeptidase, MBD, MDP, leukotriene D₄ hydrolase) is an enzyme.^[1]^[2]^[3]^[4] This enzyme catalyses the following chemical reaction

Hydrolysis of dipeptides (e.g., leukotriene D₄, cystinyl-bis-glycine, some β-lactam antibiotics (e.g., carbapenem))

This membrane-bound, zinc enzyme has broad specificity.

Inhibitors include bestatin and cilastatin.

Genes

Dipeptidase 1 (DPEP1)
Dipeptidase 2 (DPEP2)
Dipeptidase 3 (DPEP3)
