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 biosynthesis
CC pathway. {ECO:0000256|HAMAP-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 Evidence={ECO:0000256|ARBA:ARBA00000935, ECO:0000256|HAMAP-
CC Rule:MF_01695};
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01695}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase group 1 family. MshA
CC subfamily. {ECO:0000256|ARBA:ARBA00008449, ECO:0000256|HAMAP-
CC Rule:MF_01695}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
