ENZYME entry: EC 5.4.4.7

Accepted Name
hydroperoxy icosatetraenoate isomerase
Alternative Name(s)
epidermal lipoxygenase-3
Reaction catalysed
a hydroperoxyeicosatetraenoate <=> a hydroxy-epoxy-eicosatetraenoate
Comment(s)
  • The enzyme from mammals accepts a range of hydroperoxy icosatetraenoates producing one or several different hydroxy epoxy icosatrienoates.
  • The human enzyme has highest activity with (12R)-HPETE producing (5Z,8R,9E,11R,12R,14Z)-8-hydroxy-11,12-epoxyicosa-5,9,14-trienoate, followed by (12S)-HPETE producing (5Z,8Z,10R,11S,12S,14Z)-10-hydroxy- 11,12-epoxyicosa-5,8,14-trienoate and (5Z,8R,9E,11S,12S,14Z)-8- hydroxy-11,12-epoxyicosa-5,9,14-trienoate.
  • The mouse enzyme has highest activity with (8S)-HPETE, producing (5Z,8S,9S,10R,11Z,14Z)-10-hydroxy-8,9-epoxyicosa-5,11,14-trienoate.
  • The enzymes also have the activity of EC 4.2.1.152.
