Abstract
Hsp40-like co-chaperones are ubiquitous enzymes that stimulate the protein refolding activity of Hsp70 family chaperones. They are widespread in prokaryotic and eukaryotic systems. In bacteria, the best characterized co-chaperone is the Escherichia coli DnaJ protein. Many gamma-proteobacteria encode a functional homologue of DnaJ, known as CbpA, which is expressed in response to starvation and environmental stress. The activity of CbpA is regulated by the "modulator" protein CbpM. Here, we have used a combination of genetics and biochemistry to identify the co-chaperone contact determinant of CbpM. We show that the nature of the interaction is conserved in enterobacteria. (C) 2011 Elsevier Ltd. All rights reserved.
