Function
DPEP1_PIG Hydrolyzes a wide range of dipeptides (PubMed:8045301, PubMed:8823187). Hydrolyzes the conversion of leukotriene D4 to leukotriene E4. Hydrolyzes cystinyl-bis-glycine (cys-bis-gly) formed during glutathione degradation. Also possesses beta lactamase activity and hydrolytically inactivates beta-lactam antibiotics (By similarity).[UniProtKB:P31428][1] [2] Independently of its dipeptidase activity, acts as an adhesion receptor for neutrophil recruitment from bloodstream into inflamed lungs and liver.[UniProtKB:P31428]
