Function
This enzyme produces the depsipeptide D-alanyl-(R)-lactate, which can be incorporated into the peptidoglycan pentapeptide instead of the usual D-alanyl-D-alanine dipeptide. The resulting peptidoglycan does not bind the glycopeptide antibiotics vancomycin and teicoplanin, conferring resistance on the bacteria.
