Protein Variants | Comment | Organism |
---|---|---|
additional information | a msrA mutant exhibited reduced adherence to erythrocytes as well as increased sensitivity to H2O2 and tert-butyl hydroperoxide killing, the mutant is not able to survive in hamster lungs | Mycoplasma genitalium |
additional information | construction of a msrA mutant which shows drastically reduced ability to survive in macrophages compared to the wild-type strain, the mutant shows increased sensitivity to cumene hydroperoxide and tert-butyl hydroperoxide, but not to H2O2, paraquat, or sodium nitrite | Mycolicibacterium smegmatis |
additional information | construction of several mutants with reduced virulence via transposon mutagenesis involving mutation of msrA, mutation of msrA leads o increased sensitivity to oxidative agents, non-motility, and reduced spreading-out and life-span of the pathogen in plants | Dickeya chrysanthemi |
additional information | mutant strains produce a truncated version of fused MsrA/MsrB with increased sensitivity to H2O2 and superoxide anions | Neisseria gonorrhoeae |
additional information | mutation of gene msrA has no effect on virulence, and on resistance to oxidative agents, and causes no defect in cell envelope, msrA is probably linked to biofilm formation | Aggregatibacter actinomycetemcomitans |
additional information | mutation of msrA results in reduced development of mature biofilm | Escherichia coli |
additional information | mutation of the msr genes impair virulence, overview, mutation of the msrA1 operon leads to increased susceptibility to H2O2 | Staphylococcus aureus |
