... becontrolled in vivo by specific interactions betweenFadD29 and PKS15 ⁄ 1 on the one hand, and FadD26 and the FasI system on the other hand. Further inves-tigations, including protein interaction ... on the expressionof Rv2949c, abolishing the production of p-HBA,which, in turn, would suppress the synthesis ofPGL-tb in the mutant strain. To examine whether the absence of PGL-tb in the ... bio-synthesis of DIMs and PGLs, the in vivo functions ofthese FadD proteins in this pathway remain to beestablished and ⁄ or completed. For instance, the involvement of FadD26 in the biosynthesis of pheno-lphthiocerol,...
