The DnaK chaperone of Escherichia coli is known to
interact with the J domains of DnaJ, CbpA, and DjlA. By constructing
multiple mutants, we found that the djlA gene was
essential for bacterial growth above 37°C in the absence of
dnaJ. This essentiality depended upon the J domain of
DjlA but not upon the normal membrane location of DjlA.
