THE ROLE OF THE SIGMA FACTOR σs (KatF) IN BACTERIAL GLOBAL REGULATION
Abstract
The protein encoded by katF (also known as nur, appR, csi-2, abrD, and rpoS in various alleles) has been biochemically confirmed to be an alternate sigma transcription factor and renamed sigma S. Its synthesis is controlled transcriptionally and posttranscriptionally by as yet undefined mechanisms that are active well into stationary phase. sigma S controls a regulon of 30 or more genes expressed in response to starvation and during the transition to stationary phase. Proteins in the regulon, many of which have not been characterized, enhance long-term survival in nutrient-deficient medium and have a diverse group of functions including protection against DNA damage, the determination of morphological changes, the mediation of virulence, osmoprotection, and thermotolerance. Differential expression of subfamilies of genes within the regulon is effected by supplementary regulatory factors, working both individually and in combination to modulate activity of different sigma S-dependent promoters.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
