FUNCTION | Catalyzes the transfer of a 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 biosynthesis pathway. |
CATALYTIC ACTIVITY | Reaction=1D-myo-inositol 3-phosphate + UDP-N-acetyl-alpha-D-glucosamine = 1D-myo-inositol 2-acetamido-2-deoxy-alpha-D-glucopyranoside 3- phosphate + H(+) + UDP; Xref=Rhea:RHEA:26188, ChEBI:CHEBI:15378, ChEBI:CHEBI:57705, ChEBI:CHEBI:58223, ChEBI:CHEBI:58401, ChEBI:CHEBI:58892; EC=2.4.1.250; |
SUBUNIT | Homodimer. |
SIMILARITY | Belongs to the glycosyltransferase group 1 family. MshA subfamily. |
