D-alanine—(R)-lactate ligase

D-alanine—(R)-lactate ligase (, VanA, VanB, VanD) is an enzyme with systematic name D-alanine:(R)-lactate ligase (ADP-forming). This enzyme catalyses the following chemical reaction


 * D-alanine + (R)-lactate + ATP $$\rightleftharpoons$$ D-alanyl-(R)-lactate + ADP + phosphate

The product of this enzyme can be incorporated into the peptidoglycan pentapeptide instead of the usual D-alanyl-D-alanine dipeptide.
