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

Lipid metabolism; fatty acid biosynthesis.

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.
