Overexpression, purification, and characterization of VanX, a D-, D-dipeptidase which is essential for vancomycin resistance in Enterococcus faecium BM4147.

Abstract

Vancomycin resistance in Enterococcus faecium requires five genes: vanR, vanS, vanH, vanA, and vanX. The functions and mechanism of four gene products have been known, with VanR/S for signal transduction and transcriptional regulation and VanH/A to synthesize D-Ala-D-lactate. But the function of the fifth gene product, VanX, has been unknown until very recently, when Reynolds and colleagues discovered D-, D-dipeptidase activity in crude …
