Organization of heat shock dnaK and groE operons of the nosocomial pathogen Enterococcus faecium.

Enterococcus faecium is a frequently antibiotic-resistant opportunistic pathogen that is commonly recovered from hospitalized patients. The genetic organization of the dnaK operon was analyzed and was shown to consist of at least four heat shock genes, hrcA-grpE-dnaK-dnaJ. The dnaK/J intergenic region was 140 bp shorter than in E.
