| Enzyme Function | FUNCTION: Carboxypeptidase that catalyzes the release of a C-terminal amino acid, but has little or no action with -Asp, -Glu, -Arg, -Lys or -Pro (By similarity). Catalyzes the conversion of leukotriene C4 to leukotriene F4 via the hydrolysis of an amide bond (PubMed:12729612). {ECO:0000250|UniProtKB:P15085, ECO:0000269|PubMed:12729612}. |
