Enzyme Information

1.14.14.-
With reduced flavin or flavoprotein as one donor, and incorporation of one atom of oxygen.
based on mapping to UniProt P04798
4.2.1.152
Hydroperoxy icosatetraenoate dehydratase.
based on mapping to UniProt P04798
A hydroperoxy icosatetraenoate = an oxoicosatetraenoate + H(2)O.
-!- The mammalian enzymes accept a range of hydroperoxy icosatetraenoates (HPETE). -!- The human enzyme has highest activity with (12R)-HPETE, followed by (12S)-HPETE and (15R)-HPETE with much lower efficiency. -!- The murine enzyme has highest activity with (8R)-HPETE followed by (8S)-HPETE. All HPETE isoforms are converted to the corresponding oxoicosatetraenoate forms (KETE). -!- The enzymes also catalyze the reaction of EC 5.4.4.7.
