CC -!- FUNCTION: A mycothiol (MSH, N-acetylcysteinyl-glucosaminyl-inositol) S-
CC conjugate amidase, it recycles conjugated MSH to the N-acetyl cysteine
CC conjugate (AcCys S-conjugate, a mercapturic acid) and the MSH
CC precursor. Involved in MSH-dependent detoxification of a number of
CC alkylating agents and antibiotics. {ECO:0000256|HAMAP-Rule:MF_01482}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + mycothiol S-conjugate = 1D-myo-inositol 2-amino-2-deoxy-
CC alpha-D-glucopyranoside + an N-acetyl-L-cysteine-S-conjugate;
CC Xref=Rhea:RHEA:36543, ChEBI:CHEBI:15377, ChEBI:CHEBI:58718,
CC ChEBI:CHEBI:58886, ChEBI:CHEBI:59633; EC=3.5.1.115;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01482};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01482};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000256|HAMAP-Rule:MF_01482};
CC -!- SUBUNIT: Monomer. {ECO:0000256|HAMAP-Rule:MF_01482}.
CC -!- SIMILARITY: Belongs to the MshB deacetylase family. Mca subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_01482}.
