What is the function of this protein?
Part of the PpsABCDE complex involved in the biosynthesis of the lipid core common to phthiocerols and phenolphthiocerols by successive additions of malonyl-CoA or methylmalonyl-CoA extender units (PubMed:9201977).  PpsA can accept as substrate the activated forms of either icosanoyl (C20), docosanoyl (C22) or lignoceroyl (C24) groups from FadD26, or a (4-hydroxyphenyl)-C17 or (4-hydroxyphenyl)-C19 fatty acyl from FadD29 (By similarity).  PpsA initiates the biosynthesis and extends its substrate using a malonyl-CoA extender unit.  The PpsB and PpsC proteins add the second and third malonyl-CoA extender units.  PpsD adds an (R)-methylmalonyl unit and PpsE adds a second (R)-methylmalonyl unit.  The incorporation of the methylmalonyl units results in formation of two branched methyl groups in the elongated product (By similarity).
