Polyketide synthases (PKSs) of Mycobacterium tuberculosis are increasingly being seen as producers of virulence factors that are important for pathogenesis by the bacterium. Thus, the phenolphthiocerol synthase PKS cluster of M. tuberculosis is responsible, in part, for the synthesis of a virulence determinant called phthiocerol dimycocerosate (PDIM). Here, we provide evidence that the PpsE protein, which is part of that cluster, interacts with the type II thioesterase TesA of M. tuberculosis. The interaction was demonstrated by employing a two-hybrid system, and confirmed using a GST (glutathione S-transferase) pull-down' assay after both proteins had been purified to homogeneity. Based on the present findings, a revised model for the processing of polyketides during the synthesis of PDIM is presented. << Less

Mycobacterium tuberculosis cell envelope is a treasure house of biologically active lipids of fascinating molecular architecture. Although genetic studies have alluded to an array of genes in biosynthesis of complex lipids, their mechanistic, structural, and biochemical principles have not been investigated. Here, we have dissected the molecular logic underlying the biosynthesis of a virulence lipid phthiocerol dimycocerosate (PDIM). Cell-free reconstitution studies demonstrate that polyketide synthases, which are usually involved in the biosynthesis of secondary metabolites, are responsible for generating complex lipids in mycobacteria. We show that PapA5 protein directly transfers the protein bound mycocerosic acid analogs on phthiocerol to catalyze the final esterification step. Based on precise identification of biological functions of proteins from Pps cluster, we have rationally produced a nonmethylated variant of mycocerosate esters. Apart from elucidating mechanisms that generate chemical heterogeneity with PDIMs, this study also presents an attractive approach to explore host-pathogen interactions by altering mycobacterial surface coat. << Less
