Purification and characterization of VanR and the cytosolic domain of VanS: a two-component regulatory system required for vancomycin resistance in Enterococcus faecium BM4147.

Abstract

Resistance to the glycopeptide antibiotic vancomycin requires five genes. Two of these, vanR and vanS, have sequence homology to cytoplasmic response regulatory (VanR) and transmembrane sensory (VanS) proteins of two-component regulatory systems used to sense and transduce environmental signals. We report the overproduction and purification to homogeneity of VanR (27 kDa) and of a fusion protein of VanS (residues 95-374, the cytosolic domain) …
