CC -!- FUNCTION: May play a role in phthiocerol biosynthesis.
CC -!- COFACTOR:
CC Name=pantetheine 4'-phosphate; Xref=ChEBI:CHEBI:47942;
CC Evidence={ECO:0000250};
CC Note=Binds 1 phosphopantetheine covalently. {ECO:0000250};
CC -!- PATHWAY: Lipid metabolism; fatty acid biosynthesis.
CC -!- DISRUPTION PHENOTYPE: Disruption of pks1 abolishes the production of
CC phthiocerol dimycocerosate (DIM) on the cell envelope, but the
CC production of mycocerosic acid is not deficient. The pks10 mutants show
CC a major attenuation of virulence. {ECO:0000269|PubMed:12730158}.
CC -!- MISCELLANEOUS: Was identified as a high-confidence drug target.
CC -!- CAUTION: M.bovis (strains ATCC BAA-935 / AF2122/97 and BCG / Pasteur
CC 1173P2) and M.marinum (strain ATCC BAA-535 / M) have a single fused
CC pks15/1 ORF, but M.tuberculosis (strains ATCC 25618 / H37Rv and CDC
CC 1551 / Oshkosh) have 2 separate ORFs. This is due to the natural
CC deletion of a single base, a guanine, that causes a frameshift and thus
CC the two ORFs, pks15 and pks1, instead of pks15/1. This frameshift led
CC to the inactivation of Pks15/1, which in turn caused the inability of
CC these strains to elongate the putative p-hydroxybenzoic acid precursor
CC and thus to produce phenolphthiocerol derivatives. {ECO:0000305}.
