DPEP1 Lysates

DPEP1 (EC 3.4.13.11) is a kidney membrane enzyme that hydrolyzes a variety of dipeptides and is implicated in renalmetabolism of glutathione and its conjugates, e.g., leukotriene D4 (Kozak and Tate, 1982 (PubMed 6122685)). DPEP1 isresponsible for hydrolysis of the beta-lactam ring of antibiotics, such as penem and carbapenem (Campbell et al., 1984(PubMed 6334084)). Earlier, beta-lactamase enzymes were thought to occur only in bacteria, where their probablefunction was in protecting the organisms against the action of beta-lactam antibiotics. These antibiotics exhibitselective toxicity against bacteria but virtual inertness against many eukaryotic cells (Adachi et al., 1990 (PubMed2303490)).(supplied by OMIM)
