[https://www.uniprot.org/uniprot/MBTI_MYCTU MBTI_MYCTU] Mediates the production of salicylate from chorismate via an isochorismate intermediate. Presents both isochorismate synthase and isochorismate-pyruvate lyase activities. Salycilate is the starter unit in the production of the virulence-conferring salicylate-based siderophore mycobactin.<ref>PMID:16923875</ref>

== Publication Abstract from PubMed ==
 +
Mycobacterium tuberculosis salicylate synthase (MbtI), a member of the chorismate-utilizing enzyme family, catalyses the first committed step in the biosynthesis of the siderophore mycobactin T. This complex secondary metabolite is essential for both virulence and survival of M. tuberculosis, the etiological agent of tuberculosis (TB). It is therefore anticipated that inhibitors of this enzyme may serve as TB therapies with a novel mode of action. Herein we describe the first inhibition study of M. tuberculosis MbtI using a library of functionalized benzoate-based inhibitors designed to mimic the substrate (chorismate) and intermediate (isochorismate) of the MbtI-catalyzed reaction. The most potent inhibitors prepared were those designed to mimic the enzyme intermediate, isochorismate. These compounds, based on a 2,3-dihydroxybenzoate scaffold, proved to be low-micromolar inhibitors of MbtI. The most potent inhibitors in this series possessed hydrophobic enol ether side chains at C3 in place of the enol-pyruvyl side chain found in chorismate and isochorismate.
