Protein

Acyl-CoA desaturase

Gene

SCD

Organism
Ovis aries (Sheep)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli

Functioni

Terminal component of the liver microsomal stearyl-CoA desaturase system, that utilizes O2 and electrons from reduced cytochrome b5 to catalyze the insertion of a double bond into a spectrum of fatty acyl-CoA substrates including palmitoyl-CoA and stearoyl-CoA.By similarity

Catalytic activityi

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