Differential involvement of the five RNA helicases in adaptation of Bacillus cereus ATCC 14579 to low growth temperatures.
Bacillus cereus ATCC 14579 possesses five RNA helicase-encoding genes overexpressed under cold growth conditions. Out of the five corresponding mutants, only the ΔcshA, ΔcshB, and ΔcshC strains were cold sensitive. Growth of the ΔcshA strain was also reduced at 30°C but not at 37°C. The cold phenotype was restored with the cshA gene for the ΔcshA strain and partially for the ΔcshB strain but not for the ΔcshC strain, suggesting different functions at low temperature.
