1.14.19.1
Accepted name
stearoyl-CoA 9-desaturase
Reaction
stearoyl-CoA + 2 ferrocytochrome b5 + O2 + 2 H+ = oleoyl-CoA + 2 ferricytochrome b5 + 2 H2O
Other name(s)
Δ9-desaturase,
acyl-CoA desaturase,
fatty acid desaturase,
stearoyl-CoA, hydrogen-donor:oxygen oxidoreductase
Systematic name
stearoyl-CoA,ferrocytochrome-b5:oxygen oxidoreductase (9,10-dehydrogenating)
CAS registry number
9014-34-0
Comment
An iron protein. The rat liver enzyme is an enzyme system involving cytochrome b5 and EC 1.6.2.2, cytochrome-b5 reductase. The ferricytochrome b5 produced is reduced by NADH and cytochrome-b5 reductase (EC 1.6.2.2).
