Function
Required for high-level resistance to glycopeptide antibiotics. D-Ala--D-Ala ligase of altered specificity which catalyzes ester bond formation between D-Ala and various D-hydroxy acids; produces a peptidoglycan which does not terminate in D-alanine but in D-lactate, thus preventing vancomycin or teicoplanin binding
Catalytic activity
D-alanine + (R)-lactate + ATP = D-alanyl-(R)-lactate + ADP + phosphate
Cofactor
Binds 2 magnesium or manganese ions per subunit (By similarity)
Sequence similarities
Belongs to the D-alanine--D-alanine ligase family
Contains 1 ATP-grasp domain
