Diagrams illustrating the domain structure of DnaJ- and DnaK-related proteins used in this work. The p5 peptide sequence does not correspond to any part of DnaJ or DnaK. DnaJ domains are indicated as follows: J, J-domain; G/F, glycine/phenylalanine-rich domain; Zn, zinc binding domain; CTD, C-terminal domain (13). DnaK domains are indicated as follows: ATPase, ATPase domain; Linker, interdomain linker; PBdβ, β subdomain of the peptide-binding domain; PBdα, α subdomain of the peptide-binding domain.
