CC   -!- FUNCTION: Catalyzes the transfer of a N-acetyl-glucosamine moiety to
CC       1D-myo-inositol 3-phosphate to produce 1D-myo-inositol 2-acetamido-2-
CC       deoxy-glucopyranoside 3-phosphate in the mycothiol (MSH) biosynthesis
CC       pathway (By similarity). MSH and WhiB3 are probably part of a
CC       regulatory circuit that mediates gene expression upon acid stress (like
CC       that found in host macrophage phagosomes). MSH is one of the major
CC       redox buffers which protects bacteria against redox stressors and
CC       antibiotics; loss of MSH or ergothioneine (ERG, the other major redox
CC       buffer in this bacteria) leads to respiratory alterations and
CC       bioenergetic deficiencies that negatively impact virulence (By
CC       similarity). {ECO:0000250|UniProtKB:P9WMY7, ECO:0000255|HAMAP-
CC       Rule:MF_01695}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=1D-myo-inositol 3-phosphate + UDP-N-acetyl-alpha-D-glucosamine
CC         = 1D-myo-inositol 2-acetamido-2-deoxy-alpha-D-glucopyranoside 3-
CC         phosphate + H(+) + UDP; Xref=Rhea:RHEA:26188, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:57705, ChEBI:CHEBI:58223, ChEBI:CHEBI:58401,
CC         ChEBI:CHEBI:58892; EC=2.4.1.250;
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the glycosyltransferase group 1 family. MshA
CC       subfamily. {ECO:0000305}.
