Comments [?]

Function Catalyzes the deacetylation of 1D-myo-inositol 2-acetamido-2-deoxy-alpha-D-glucopyranoside (GlcNAc-Ins) in the mycothiol biosynthesis pathway.
Catalytic activity RHEA:26180: 1D-myo-inositol 2-acetamido-2-deoxy-alpha-D-glucopyranoside + H2O = 1D-myo-inositol 2-amino-2-deoxy-alpha-D-glucopyranoside + acetate
EC 3.5.1.103
Cofactor Zn(2+)
Note: Binds 1 zinc ion per subunit.
Similarity Belongs to the MshB deacetylase family.
