CC -!- FUNCTION: Involved in bacillithiol (BSH) biosynthesis. Catalyzes the
CC first step of the pathway, the formation of N-acetylglucosaminylmalate
CC (GlcNAc-Mal) from UDP-N-acetylglucosamine (UDP-GlcNAc) and L-malate.
CC {ECO:0000269|PubMed:20308541, ECO:0000269|PubMed:22569254}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(S)-malate + UDP-N-acetyl-alpha-D-glucosamine = (S)-malyl N-
CC acetyl-alpha-D-glucosaminide + H(+) + UDP; Xref=Rhea:RHEA:33383,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:15589, ChEBI:CHEBI:57705,
CC ChEBI:CHEBI:58223, ChEBI:CHEBI:64870;
CC Evidence={ECO:0000269|PubMed:20308541, ECO:0000269|PubMed:22569254};
CC -!- ACTIVITY REGULATION: Inhibited by BSH. {ECO:0000269|PubMed:22569254}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=0.41 mM for L-malate {ECO:0000269|PubMed:22569254};
CC KM=0.37 mM for UDP-GlcNAc {ECO:0000269|PubMed:22569254};
CC Vmax=11200 nmol/min/mg enzyme toward L-malate
CC {ECO:0000269|PubMed:22569254};
CC Vmax=8700 nmol/min/mg enzyme toward UDP-GlcNAc
CC {ECO:0000269|PubMed:22569254};
CC -!- SUBUNIT: Homotetramer. {ECO:0000269|PubMed:22569254}.
CC -!- DISRUPTION PHENOTYPE: Mutant does not produce bacillithiol.
CC {ECO:0000269|PubMed:20308541}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase group 1 family.
CC Glycosyltransferase 4 subfamily. {ECO:0000305}.
