DnaK chaperone machine and trigger factor are only partially required for normal growth of Bacillus subtilis.
While dnaK and tig are the essential components for nascent polypeptide folding in E. coli, deletion did not confer synthetic lethality in B. subtilis, suggesting that under normal growth conditions, another system or mechanism with a specific role prevails. Likewise, survival at high temperature suffered dramatically, resulting from deletion of several sets of heat shock genes, thus during sudden stress various heat shock genes act synergistically to protect the proteins.
