Deletion of the sigB gene in Bacillus cereus ATCC 14579 leads to hydrogen peroxide hyperresistance.
نویسندگان
چکیده
The sigB gene of Bacillus cereus ATCC 14579 encodes the alternative sigma factor sigma(B). Deletion of sigB in B. cereus leads to hyperresistance to hydrogen peroxide. The expression of katA, which encodes one of the catalases of B. cereus, is upregulated in the sigB deletion mutant, and this may contribute to the hydrogen peroxide-resistant phenotype.

The presence of SigB in Listeria monocytogenes leads to hypersensitivity to hydrogen peroxide under aerobic conditions
Background: SigB is the main stress gene regulator in L. monocytogenes affecting the expression of more than 150 genes and thus contributing in multiple stress resistance. Despite its clear role in most stresses, there is a disambiguation regarding its role against oxidative stress with results ranging from hyperresistance to hypersensitivity that accompanies the loss of sigB. This discrepancy ...
متن کاملComparative transcriptomic and phenotypic analysis of the responses of Bacillus cereus to various disinfectant treatments.
Antimicrobial chemicals are widely applied to clean and disinfect food-contacting surfaces. However, the cellular response of bacteria to various disinfectants is unclear. In this study, the physiological and genome-wide transcriptional responses of Bacillus cereus ATCC 14579 exposed to four different disinfectants (benzalkonium chloride, sodium hypochlorite, hydrogen peroxide, and peracetic ac...
متن کاملDifferential 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 no...
متن کاملCloning, Purification and Characterization of the Collagenase ColA Expressed by Bacillus cereus ATCC 14579
Bacterial collagenases differ considerably in their structure and functions. The collagenases ColH and ColG from Clostridium histolyticum and ColA expressed by Clostridium perfringens are well-characterized collagenases that cleave triple-helical collagen, which were therefore termed as ´true´ collagenases. ColA from Bacillus cereus (B. cereus) has been added to the collection of true collagena...
متن کاملorf4 of the Bacillus cereus sigB gene cluster encodes a general stress-inducible Dps-like bacterioferritin.
The function of orf4 in the sigB cluster in Bacillus cereus ATCC 14579 remains to be explored. Amino-acid sequence analysis has revealed that Orf4 is homologous with bacterioferritins and Dps. In this study, we generated an orf4-null mutant and produced recombinant protein rOrf4 to establish the role of orf4. In vitro, the purified rOrf4 was found to exist in two distinct forms, a dimeric form ...
