Characterization of the vanD glycopeptide resistance gene cluster from Enterococcus faecium BM4339.
The study characterizes the vanD glycopeptide resistance gene cluster in Enterococcus faecium BM4339, identifying several genes including vanD, vanH, vanX, vanY, vanR, and vanS, which collectively confer resistance to glycopeptide antibiotics through the synthesis of d-alanyl-d-lactate-terminating peptidoglycan precursors.

VanD-Type Vancomycin-Resistant Enterococcus faecium 10/96A.
The study identifies the vanD gene cluster in Enterococcus faecium 10/96A, which confers vancomycin resistance through the synthesis of peptidoglycan precursors ending in d-Ala-d-Lac. A G184S mutation in the ddl gene impairs the d-Ala:d-Ala ligase, contributing to resistance.
