Accepted name: leukotriene-E4 20-monooxygenase

Reaction: (7E,9E,11Z,14Z)-(5S,6R)-6-(cystein-S-yl)-5-hydroxyicosa-7,9,11,14-tetraenoate + NADPH + H+ + O2 = 20-hydroxyleukotriene E4 + NADP+ + H2O

Other name(s): leukotriene-E4 ω-hydroxylase

Systematic name: (7E,9E,11Z,14Z)-(5S,6R)-6-(cystein-S-yl)-5-hydroxyicosa-7,9,11,14-tetraenoate,NADPH:oxygen oxidoreductase (20-hydroxylating)

Comments: Also acts on N-acetyl-leukotriene E4, but more slowly. Not identical with EC leukotriene-B4 20-monooxygenase.
