General annotation (Comments)

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. HAMAP MF_00047

Cofactor

Binds 2 magnesium or manganese ions per subunit By similarity.

Subcellular location

Cell membrane; Peripheral membrane protein; Cytoplasmic side. HAMAP MF_00047

Induction

By vancomycin, mediated by vanS/vanR. HAMAP MF_00047

Sequence similarities

Belongs to the D-alanine--D-alanine ligase family.

Contains 1 ATP-grasp domain.
