Phenolphthiocerol/phthiocerol polyketide synthase subunit E
ppsE
Functioni
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. 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. 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.
