Overlapping homologous superfamilies

Domain relationships



These proteins are metallopeptidases belonging to MEROPS peptidase family M15 (clan MD), subfamily M15B (vanY D-Ala-D-Ala carboxypeptidase).

Acquired VanA- and VanB-type glycopeptide resistance in enterococci is due to synthesis of modified peptidoglycan precursors terminating in D-lactate. As opposed to VanA-type strains which are resistant to both vancomycin and teicoplanin, VanB-type strains remain teicoplanin susceptible [PMID: 8631706]. The vanY gene was necessary for synthesis of the vancomycin-inducible D,D-carboxypeptidase EC: activity previously proposed to be responsible for glycopeptide resistance. However, this activity was not required for peptidoglycan synthesis in the presence of glycopeptides [PMID: 1398115].
