RpoS, like other sigma factors, associates with core RNA polymerase (RNAP or E), enabling RNAP promoter recognition during initiation of transcription [ 19 – 21 ].

WebMar 1, 2024 · The latter region of RpoD had increased binding to an anti-sigma factor AsiA (Sharma et al., 1999) which is similar to the E. coli anti-sigma factor Rsd (Hofmann et al., 2011). The mutation found in our studies in region 4 of mutant 2 (Y571F) lies within the region that binds to PhoB at the pho boxes (amino acids 570–592), which is present in ...

WebApr 21, 2024 · Furthermore, we found that overexpression of algU prevents cell growth in the absence of MucA, and that this phenotype can be rescued by overproduction of RpoD, the housekeeping sigma factor. Together, these results suggest that in the absence of MucA, the inability to regulate AlgU activity results in the loss of bacterial viability.
