Protein attributes
| Sequence length | 2188 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Involved in the elongation of either C22-24 fatty acids or p-hydroxyphenylalkanoic acids by the addition of malonyl-CoA and methylmalonyl-CoA extender units to yield phthiocerol and phenolphthiocerol derivatives, respectively. Ref.2 |
| Catalytic activity | Acyl-[acyl-carrier-protein] + malonyl-[acyl-carrier-protein] = 3-oxoacyl- [acyl-carrier-protein] + CO2 + [acyl-carrier-protein]. |
| Cofactor | Binds 1 phosphopantetheines covalently By similarity. NADP By similarity. |
| Pathway | |
| Subunit structure | Homodimer By similarity. |
| Disruption phenotype | Cells lacking this genes abolish the production of phenolphthiocerol derivative (mycoside B) and phthiocerol dimycocerosates (DIM) on the cell envelope. Ref.2 |
| Sequence similarities | Contains 1 acyl carrier domain. |
