DOI: 10.1007/s11306-017-1296-6
Abstract: IntroductionClpXP protease is an important proteolytic system in Salmonella enterica serovar typhimurium (S. typhimurium). Inactivation of ClpXP by deletion of clpP resulted in overproduction of RpoS and a growth defect phenotype. Only one report has… read more here.

DOI: 10.1093/nar/gkaf103
Abstract: Abstract The RNA-binding protein ProQ interacts with many transcripts in the bacterial cell. ProQ binding is associated with increased messenger RNA (mRNA) levels, but a mechanistic explanation for this effect has been lacking. In Salmonella… read more here.

DOI: 10.1101/2024.07.11.603030
Abstract: Mutation rate varies within and between genomes. Within genomes, tracts of nucleotides, including short sequence repeats and palindromes, can cause localised elevation of mutation rate. Additional mechanisms remain poorly understood. Here we report an instance… read more here.

DOI: 10.1128/jb.00009-19
Abstract: The Q fever bacterium Coxiella burnetii has spore-like environmental stability, a characteristic that contributes to its designation as a potential bioweapon. Stability is likely conferred by a highly resistant, small cell variant (SCV) stationary-phase form… read more here.

DOI: 10.1128/mbio.01204-17
Abstract: ABSTRACT The alternative sigma factor RpoS plays a key role modulating gene expression in Borrelia burgdorferi, the Lyme disease spirochete, by transcribing mammalian host-phase genes and repressing σ70-dependent genes required within the arthropod vector. To… read more here.
