CC -!- FUNCTION: Part of the PpsABCDE complex involved in the biosynthesis of
CC the lipid core common to phthiocerols and phenolphthiocerols by
CC successive additions of malonyl-CoA or methylmalonyl-CoA extender
CC units. PpsA can accept as substrate the activated forms of either
CC icosanoyl (C20), docosanoyl (C22) or lignoceroyl (C24) groups from
CC FadD26, or a (4-hydroxyphenyl)-C17 or (4-hydroxyphenyl)-C19 fatty acyl
CC from FadD29. PpsA initiates the biosynthesis and extends its substrate
CC using a malonyl-CoA extender unit. The PpsB and PpsC proteins add the
CC second and third malonyl-CoA extender units. PpsD adds an (R)-
CC methylmalonyl unit and PpsE adds a second (R)-methylmalonyl unit. The
CC incorporation of the methylmalonyl units results in formation of two
CC branched methyl groups in the elongated product.
CC {ECO:0000250|UniProtKB:P9WQE3}.
