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:0000256|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 ChEBI:CHEBI:52442, ChEBI:CHEBI:58886; EC=3.5.1.103;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01696};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01696};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000256|HAMAP-Rule:MF_01696};
CC -!- SIMILARITY: Belongs to the MshB deacetylase family. {ECO:0000256|HAMAP-
CC Rule:MF_01696}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
