Notes
ATP-regulated binding and release of polypeptide substrates. Binds Zn(II). DnaJ is co-chaperone. Role in the initiation of DNA replication. DnaK has secondary amide peptide bond cis-trans isomerase (APIase) activity. A dnaK mutant is inviable above 42C, or below 8C (as enabled by transgenic Oleispira antarctica Cpn10/60). Delta tig delta dnaK mutants are synthetic lethal at 30 degrees C, however, no lethal effects are observed at 23 degrees C; overproduction of GroEL/GroES at 30 degrees C supresses synthetic lethality. dnaK, hscA, hscC and yegD are paralogs. HT_Cmplx22_Cyt: DnaK+GrpE+GyrA+RpsA. HT_Cmplx30_Mem: ClpB+DnaK+InfB+RpsA. After four hours of Zn(II) stress, protein levels increased (Easton, 2006).[4]
