CC   -!- FUNCTION: Required for high-level resistance to glycopeptides
CC       antibiotics. Catalyzes the reduction of 2-keto acids to 2-D-hydroxy
CC       acids that give rise to peptidoglycan precursors that terminate in the
CC       depsipeptide D-alanine-2-lactate rather than the dipeptide D-alanine-D-
CC       alanine thus preventing vancomycin binding.
CC   -!- INDUCTION: By vancomycin, mediated by VanS/VanR. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the D-isomer specific 2-hydroxyacid
CC       dehydrogenase family. {ECO:0000305}.
