Function
This enzyme is required for high-level resistance to glycopeptides antibiotics. D-Ala--D-Ala ligase of altered specificity catalyzes ester bond formation between D-Ala and various D-hydroxy acids and produce a peptidoglycan which does not terminate in D-alanine but in D-lactate, thus preventing vancomycin binding.
KEGG Pathway
Two-component system (efa02020 )
Vancomycin resistance (efa01502 )
