Popis: Hsp70 proteins and their Hsp40 co‐chaperones are essential components of cellular chaperone networks in both prokaryotes and eukaryotes. Here, we performed a genetic analysis to define the protein domains required for the key functions of the major Hsp40/DnaJ protein Sll0897 of the cyanobacterium Synechocystis sp. PCC6803. The expression of the N‐terminally located J‐ and G/F‐domains is essential and sufficient for the proteins’ fundamental in vivo functions, whereas the presence of the full‐length protein, containing the C‐terminal substrate‐binding domains, is crucial under stress conditions.
