Protein

Acyl-CoA desaturase

Gene

OLE1

Organism
Ajellomyces capsulatus (Darling's disease fungus) (Histoplasma capsulatum)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Utilizes O2 and electrons from the reduced cytochrome b5 domain to catalyze the insertion of a double bond into a spectrum of fatty acyl-CoA substrates.

Catalytic activityi

Stearoyl-CoA + 2 ferrocytochrome b5 + O2 + 2 H+ = oleoyl-CoA + 2 ferricytochrome b5 + 2 H2O.
