Function
function
Cytochromes P450 are a group of heme-thiolate monooxygenases. They oxidize a variety of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics.
Catalytic activity
- (12S)-hydroperoxy-(5Z,8Z,10E,14Z)-eicosatetraenoate = 12-oxo-(5Z,8Z,10E,14Z)-eicosatetraenoate + H2OThis reaction proceeds in the forward direction.
- (13S)-hydroperoxy-(9Z,11E)-octadecadienoate = 13-oxo-(9Z,11E)-octadecadienoate + H2OThis reaction proceeds in the forward direction.
- (15S)-hydroperoxy-(5Z,8Z,11Z,13E)-eicosatetraenoate = 15-oxo-(5Z,8Z,11Z,13E)-eicosatetraenoate + H2OThis reaction proceeds in the forward direction.
- (4Z,7Z,10Z,13Z,16Z,19Z)-docosahexaenoate + reduced [NADPH--hemoprotein reductase] + O2 = (19R,20S)-epoxy-(4Z,7Z,10Z,13Z,16Z)-docosapentaenoate + oxidized [NADPH--hemoprotein reductase] + H2O + H+This reaction proceeds in the forward direction.
- (5S)-hydroperoxy-(6E,8Z,11Z,14Z)-eicosatetraenoate = 5-oxo-(6E,8Z,11Z,14Z)-eicosatetraenoate + H2OThis reaction proceeds in the forward direction.

- (5Z,8Z,11Z,14Z)-eicosatetraenoate + reduced [NADPH--hemoprotein reductase] + O2 = 19-hydroxy-(5Z,8Z,11Z,14Z)-eicosatetraenoate + oxidized [NADPH--hemoprotein reductase] + H2O + H+This reaction proceeds in the forward direction.
- (5Z,8Z,11Z,14Z,17Z)-eicosapentaenoate + reduced [NADPH--hemoprotein reductase] + O2 = (17R,18S)-epoxy-(5Z,8Z,11Z,14Z)-eicosatetraenoate + oxidized [NADPH--hemoprotein reductase] + H2O + H+This reaction proceeds in the forward direction.
- 17beta-estradiol + reduced [NADPH--hemoprotein reductase] + O2 = 2-hydroxy-17beta-estradiol + oxidized [NADPH--hemoprotein reductase] + H2O + H+This reaction proceeds in the forward direction.
- 17beta-estradiol + reduced [NADPH--hemoprotein reductase] + O2 = 4-hydroxy-17beta-estradiol + oxidized [NADPH--hemoprotein reductase] + H2O + H+This reaction proceeds in the forward direction.
- all-trans-retinal + reduced [NADPH--hemoprotein reductase] + O2 = all-trans-retinoate + oxidized [NADPH--hemoprotein reductase] + H2O + 2 H+This reaction proceeds in the forward direction.
- all-trans-retinol + reduced [NADPH--hemoprotein reductase] + O2 = all-trans-retinal + oxidized [NADPH--hemoprotein reductase] + 2 H2O + H+This reaction proceeds in the forward direction.
- estrone + reduced [NADPH--hemoprotein reductase] + O2 = 2-hydroxyestrone + oxidized [NADPH--hemoprotein reductase] + H2O + H+This reaction proceeds in the forward direction.
- estrone + reduced [NADPH--hemoprotein reductase] + O2 = 4-hydroxyestrone + oxidized [NADPH--hemoprotein reductase] + H2O + H+This reaction proceeds in the forward direction.
