==Introduction==
 
-
''Mycobacterim tuberculosis'' salicylate synthase (MtbI) is a highly promiscuous enzyme that has four distinct activities: isochorismate synthase (IS), isochorismate pyruvate lyase (IPL), salicylate synthase (SS) and chromate mutate (CM). MtbI belongs to the MST enzyme family, which consists of structural homologues (Irp9, MenF, EntC, and MtbI) that isomerize chromate to isochorismate.

==Structure==
 
-
The crystal asymmetric unit was found to contain <scene name='69/694235/3log/1'> four MbtI molecules</scene>, however crystal packing and size exclusion chromatography data suggest a monomeric enzyme. There are no significant structural changes between the four monomers excepts from the localized differences in the active site. The overall molecular structure consist of a polypeptide of 450 residues that forms one large single domain with a similar fold to other chromate-utilizing enzymes. The core of the protein is formed by 21 beta-strands folded into a twisted beta-sandwich. The protein's core is then surrounded by 10 alpha helices.

The salicylate synthase activity of MbtI produces salicylate from chorismate through an isochorismate intermediate. This reaction is Mg dependent. Chorismate is then used in the biosyntheses of Mycobactin T, the siderophore of ''M. tuberculosis''. The siderophore sequesters iron, covering pathogenesis of'' M. tuberculosis''.
