General annotation (Comments)
| Function | Fatty acid delta-9-desaturase that introduces a double bond in fatty acyl-coenzyme A at the delta-9 position. Ref.7 |
| Catalytic activity | Stearoyl-CoA + 2 ferrocytochrome b5 + O2 + 2 H+ = oleoyl-CoA + 2 ferricytochrome b5 + 2 H2O. |
| Cofactor | Iron By similarity. |
| Subcellular location | Endoplasmic reticulum membrane; Multi-pass membrane protein Ref.7. |
| Tissue specificity | Detected in fetal brain, and at lower levels in fetal kidney. Detected in adult brain and pancreas, and at lower levels in kidney and lung. Ref.1 Ref.7 |
| Domain | The histidine box domains may contain the active site and/or be involved in metal ion binding By similarity. |
| Sequence similarities | Belongs to the fatty acid desaturase family. |
