CC   -!- FUNCTION: Catalyzes the deacetylation of 1D-myo-inositol 2-acetamido-2-
CC       deoxy-alpha-D-glucopyranoside (GlcNAc-Ins) in the mycothiol
CC       biosynthesis pathway. {ECO:0000255|HAMAP-Rule:MF_01696}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=1D-myo-inositol 2-acetamido-2-deoxy-alpha-D-glucopyranoside +
CC         H2O = 1D-myo-inositol 2-amino-2-deoxy-alpha-D-glucopyranoside +
CC         acetate; Xref=Rhea:RHEA:26180, ChEBI:CHEBI:15377, ChEBI:CHEBI:30089,

CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01696};
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01696};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01696};
CC   -!- SIMILARITY: Belongs to the MshB deacetylase family. {ECO:0000255|HAMAP-
CC       Rule:MF_01696}.
