Genetic and biochemical characterization of mutations affecting the carboxy-terminal domain of the Escherichia coli molecular chaperone DnaJ.

DnaJ is a universally conserved heat shock protein involved in protein folding. DnaJ contains four conserved domains. The N-terminal 'J-domain' has been shown to be responsible for the recruitment of its specific DnaK partner protein. The 'Gly/Phe'- and 'Cys-rich' domains have been implicated in stabilizing interactions with DnaK. DnaJ is also able to… CONTINUE READING
