Key enzymes in the biosynthesis of MSH in M. tuberculosis include the glycosyltransferase (MshA, encoded by Rv0486), the GlcNAc-Ins deacetylase (MshB, encoded by Rv1170), the ATP-dependent Cys:GlcN-Ins ligase (MshC, encoded by Rv2130c), and the acetyl-CoA (CoASAc):Cys-GlcN-Ins acetyltransferase (MSH synthase; MshD, encoded by Rv0819).
