1D-myo-inositol 2-acetamido-2-deoxy-alpha-D-glucopyranoside deacetylase; Catalyzes the deacetylation of 1D-myo-inositol 2-acetamido-2- deoxy-alpha-D-glucopyranoside (GlcNAc-Ins) in the mycothiol (MSH) biosynthesis pathway. Shows some amidase activity toward S-conjugates of mycothiol; Belongs to the MshB deacetylase family.

Glycosyltransferase MshA; Catalyzes the transfer of an N-acetyl-glucosamine moiety to 1D-myo-inositol 3-phosphate to produce 1D-myo-inositol 2-acetamido-2- deoxy-glucopyranoside 3-phosphate in the mycothiol (MSH) biosynthesis pathway. MSH and WhiB3 are probably part of a regulatory circuit that mediates gene expression upon acid stress (like that found in host macrophage phagosomes). MSH is one of the major redox buffers which protects bacteria against redox stressors and antibiotics; loss of MSH or ergothioneine (ERG, the other major redox buffer in this bacteria) leads to respiratory [...]

Mycothiol conjugate amidase Mca (mycothiol S-conjugate amidase); A mycothiol (MSH, N-acetyl-cysteinyl-glucosaminyl-inositol) S-conjugate amidase, it recycles conjugated MSH to the N-acetyl cysteine conjugate and the MSH precursor. Involved in MSH-dependent detoxification of a number of alkylating agents and antibiotics. Activity is specific for the mycothiol moiety. Has a low but measurable deacetylation activity on GlcNAc-Ins (N-acetyl-glucosaminyl-inositol), and thus can also directly contribute to the production of MSH.
