Protein
4'-phosphopantetheinyl transferase Sfp
Organism
Bacillus subtilis (strain 168)
Function
Activates the seven peptidyl carrier protein (PCP) domains of the first three subunits (SrfAA, SrfAB and SrfAC) of surfactin synthetase by transferring the 4'-phosphopantetheinyl moiety of coenzyme A (CoA) to a serine residue. Required for cells of B.subtilis to become producers of the lipopeptide antibiotics surfactin and plipastatin B1.
Similarity
Belongs to the P-Pant transferase superfamily. Gsp/Sfp/HetI/AcpT family.
