| Enzyme Function | FUNCTION: Hydrolyzes a wide range of dipeptides including the conversion of leukotriene D4 to leukotriene E4 (PubMed:2303490, PubMed:6334084, PubMed:31442408). Hydrolyzes cystinyl-bis-glycine (cys-bis-gly) formed during glutathione degradation (By similarity). Possesses also beta lactamase activity and hydrolytically inactivates beta-lactam antibiotics (PubMed:6334084). {ECO:0000250|UniProtKB:P31428, ECO:0000269|PubMed:2303490, ECO:0000269|PubMed:31442408, ECO:0000269|PubMed:6334084}.; FUNCTION: Independently of its dipeptidase activity, acts as an adhesion receptor for neutrophil recruitment from bloodstream into inflamed lungs and liver. {ECO:0000250|UniProtKB:P31428}. |
