Roles of alkyl hydroperoxide reductase subunit C (AhpC) in viable but nonculturable Vibrio parahaemolyticus.
Alkyl hydroperoxide reductase subunit C (AhpC) is the catalytic subunit responsible for the detoxification of reactive oxygen species that form in bacterial cells or are derived from the host; thus, AhpC facilitates the survival of pathogenic bacteria under environmental stresses or during infection. This study investigates the role of AhpC in the induction and maintenance of a viable but noncu...
متن کاملNADH oxidase and alkyl hydroperoxide reductase subunit C (peroxiredoxin) from Amphibacillus xylanus form an oligomeric assembly
The NADH oxidase-peroxiredoxin (Prx) system of Amphibacillus xylanus reduces hydroperoxides with the highest turnover rate among the known hydroperoxide-scavenging enzymes. The high electron transfer rate suggests that there exists close interaction between NADH oxidase and Prx. Variant enzyme experiments indicated that the electrons from β-NADH passed through the secondary disulfide, Cys128-Cy...
متن کاملpreparative sds-page electroelution for rapid purification of alkyl hydroperoxide reductase from helicobacter pylori
background: alkyl hydroperoxide reductase (ahpc) of helicobacter pylori is considered as a diagnostic antigen. therefore, this antigen can be used to detect h. pylori infection by stool immunoassays such as elisa. the aim of this study was to simplify the ahpc protein purification procedures. methods: for whole cell protein extraction, the bacterial cells were ruptured by octly-β-d glucopyrano...
متن کاملActivities of Alkyl Hydroperoxide Reductase Subunits C1 and C2 of Vibrio parahaemolyticus against Different Peroxides.
Alkyl hydroperoxide reductase subunit C gene (ahpC) functions were characterized in Vibrio parahaemolyticus, a commonly occurring marine food-borne enteropathogenic bacterium. Two ahpC genes, ahpC1 (VPA1683) and ahpC2 (VP0580), encoded putative two-cysteine peroxiredoxins, which are highly similar to the homologous proteins of Vibrio vulnificus. The responses of deletion mutants of ahpC genes t...
متن کاملRole of Alkyl Hydroperoxide Reductase (AhpC) in the Biofilm Formation of Campylobacter jejuni
Biofilm formation of Campylobacter jejuni, a major cause of human gastroenteritis, contributes to the survival of this pathogenic bacterium in different environmental niches; however, molecular mechanisms for its biofilm formation have not been fully understood yet. In this study, the role of oxidative stress resistance in biofilm formation was investigated using mutants defective in catalase (...
