RL Submitted (JAN-2010) to the EMBL/GenBank/DDBJ databases.
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:0000255|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; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01695};
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01695}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase group 1 family. MshA
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_01695}.
