General annotation (Comments)

Function

Hydrolyzes an epoxide moiety of LTA4 to form LTB4. The enzyme also has some peptidase activity By similarity.

Catalytic activity

(7E,9E,11Z,14Z)-(5S,6S)-5,6-epoxyicosa-7,9,11,14-tetraenoate + H2O = (6Z,8E,10E,14Z)-(5S,12R)-5,12-dihydroxyicosa-6,8,10,14-tetraenoate.

Cofactor

Binds 1 zinc ion per subunit By similarity.

Pathway

Lipid metabolism; leukotriene B4 biosynthesis.

Subcellular location

Cytoplasm By similarity. Nucleus By similarity.

Sequence similarities

Belongs to the peptidase M1 family.

Sequence caution

The sequence EDK42232.1 differs from that shown. Reason: Erroneous gene model prediction.
