| EC Number | 3.4.13.19; 3.5.2.6 |
| Enzyme Function | FUNCTION: Hydrolyzes a wide range of dipeptides including the conversion of leukotriene D4 to leukotriene E4. Hydrolyzes cystinyl-bis-glycine (cys-bis-gly) formed during glutathione degradation. Possesses also beta lactamase activity and hydrolytically inactivates beta-lactam antibiotics. {ECO:0000250|UniProtKB:P31428}.; 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}. |
