Abstract

Summary: The ability of a bacterial cell to monitor and adaptively respond to its environment is crucial for survival. After one‐ and two‐component systems, extracytoplasmic function (ECF) σ factors – the largest group of alternative σ factors – represent the third fundamental mechanism of bacterial signal transduction, with about six such regulators on average per bacterial genome. Together with their cognate anti‐σ factors, they represent a highly modular design that primarily facilitates transmembrane signal transduction. A comprehensive analysis of the ECF σ factor protein family identified more than 40 distinct major groups of ECF σ factors. The functional relevance of this classification is supported by the sequence similarity and domain architecture of cognate anti‐σ factors, genomic context conservation, and potential target promoter motifs. Moreover, this phylogenetic analysis revealed unique features indicating novel mechanisms of ECF‐mediated signal transduction. This classification, together with the web tool ECF finder and the information stored in the Microbial Signal Transduction (MiST) database, provides a comprehensive resource for the analysis of ECF σ factor‐dependent gene regulation.

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.
