RL Submitted (MAY-2016) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes the transfer of acetyl from acetyl-CoA to
CC desacetylmycothiol (Cys-GlcN-Ins) to form mycothiol.
CC {ECO:0000256|HAMAP-Rule:MF_01698}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=1D-myo-inositol 2-(L-cysteinylamino)-2-deoxy-alpha-D-
CC glucopyranoside + acetyl-CoA = CoA + H(+) + mycothiol;
CC Xref=Rhea:RHEA:26172, ChEBI:CHEBI:15378, ChEBI:CHEBI:16768,
CC ChEBI:CHEBI:57287, ChEBI:CHEBI:57288, ChEBI:CHEBI:58887;
CC EC=2.3.1.189; Evidence={ECO:0000256|HAMAP-Rule:MF_01698};
CC -!- SUBUNIT: Monomer. {ECO:0000256|HAMAP-Rule:MF_01698}.
CC -!- SIMILARITY: Belongs to the acetyltransferase family. MshD subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_01698}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01698}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:GAT81807.1}.
