A brief summary of the role of DnaK and GroE chaperones in protein folding precedes a discussion of the role of GroE in Escherichia coli. We consider its obligate substrates, the 8 that are both obligate and essential, and the prospects for constructing a mutant that could survive without it. Structural features of GroE-dependent polypeptides are also considered.
