Function

function

A cytochrome P450 monooxygenase involved in the metabolism of fatty acids. Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (NADPH--hemoprotein reductase). Catalyzes the hydroxylation of carbon-hydrogen bonds. Hydroxylates fatty acids specifically at the omega-1 position displaying the highest catalytic activity for saturated fatty acids. May be involved in the oxidative metabolism of xenobiotics.

Catalytic activity

  • (4Z,7Z,10Z,13Z,16Z,19Z)-docosahexaenoate + O2 + reduced [NADPH--hemoprotein reductase] = 21-hydroxy-(4Z,7Z,10Z,13Z,16Z,19Z)-docosahexaenoate + H+ + H2O + oxidized [NADPH--hemoprotein reductase]
    This reaction proceeds in the forward direction.
  • (5Z,8Z,11Z)-eicosatrienoate + O2 + reduced [NADPH--hemoprotein reductase] = 19-hydroxy-(5Z,8Z,11Z)-eicosatrienoate + H+ + H2O + oxidized [NADPH--hemoprotein reductase]
    This reaction proceeds in the forward direction.
  • (5Z,8Z,11Z,14Z,17Z)-eicosapentaenoate + O2 + reduced [NADPH--hemoprotein reductase] = 19-hydroxy-(5Z,8Z,11Z,14Z,17Z)-eicosapentaenoate + H+ + H2O + oxidized [NADPH--hemoprotein reductase]
    This reaction proceeds in the forward direction.
  • O2 + reduced [NADPH--hemoprotein reductase] + tetradecanoate = 13-hydroxytetradecanoate + H+ + H2O + oxidized [NADPH--hemoprotein reductase]
    This reaction proceeds in the forward direction.
  • an organic molecule + O2 + reduced [NADPH--hemoprotein reductase] = an alcohol + H+ + H2O + oxidized [NADPH--hemoprotein reductase]
    This reaction proceeds in the forward direction.
