Comments [?]

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 RHEA:26188: 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
Subunit Homodimer.
Similarity Belongs to the glycosyltransferase group 1 family. MshA subfamily.
