General annotation (Comments)

Function

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 activity

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

Cofactor

Iron.

Subcellular location

Endoplasmic reticulum membrane; Multi-pass membrane protein Probable.

Domain

The histidine box domains may contain the active site and/or be involved in metal ion binding.

Sequence similarities

Belongs to the fatty acid desaturase family.
