Extracytoplasmic function (ECF) sigma factors constitute a diverse family of proteins, within the class of the sigma 70 subunit of RNA polymerase. Most members of the family studied to date are known to regulate gene expression in response to stress conditions. The Bacillus subtilis genome encodes at least 17 distinct sigma factors, seven of which are members of the ECF subfamily. Among these, five sigma factors, namely SigV, SigW, SigX, SigY and SigM, are encoded by the first genes of the…

Glucose Induces ECF Sigma Factor Genes, sigX and sigM, Independent of Cognate Anti-sigma Factors through Acetylation of CshA in Bacillus subtilis

A model wherein glucose addition results in a larger acetyl-CoA pool, probably leading to increased levels of acetylated CshA is presented, showing a functional link between nutritional signals and the basal transcription machinery.

It is demonstrated that the mechanisms of ECF-dependent signaling are divergent and constitute a multi-layered hierarchy, and useful insights are provided into the elucidation of unknown mechanisms related to ECF sigma factors.

The Enterococcus faecalis SigV Protein Is an Extracytoplasmic Function Sigma Factor Contributing to Survival following Heat, Acid, and Ethanol Treatments

Two genes whose protein products showed 33 and 34% identity with those of sigV and yrhM of Bacillus subtilis are predicted to encode members of the extracytoplasmic function subfamily of eubacterial RNA polymerase sigma and anti-sigma factors, respectively.

Repression of the activities of two extracytoplasmic function σ factors, σM and σV, of Bacillus subtilis by glucolipids in Escherichia coli cells.

In Bacillus subtilis ugtP null mutant cells, three of the seven ECF σ factors, σM, ρV and σX, are activated and glucolipids directly influence anti-σM andAnti-σV factors by stabilizing conformations that sequester the respective ECFπ factors.

Transcriptional analysis of the ylaABCD operon of Bacillus subtilis encoding a sigma factor of extracytoplasmic function family.

Experiments with yLAD-disruption or co-overexpression of ylaD with ylaC suggested that YlaD functions as the anti-YlaC factor as it has an oxidative stress sensing domain similar to that of the RsrA, which is theAnti-sigma factor of SigR, an ECF sigma of Streptomyces coelicolor.

Structural analysis of the recognition of the -35 promoter element by SigW from Bacillus subtilis

The crystal structure of the σ4 domain of Bacillus subtilis SigW bound to the -35 promoter element is reported and it is revealed that DNA recognition and anti-sigma factor binding of SigW are mutually exclusive.

Structural analysis of the recognition of the -35 promoter element by SigW from Bacillus subtilis.

The crystal structure of the σ4 domain of Bacillus subtilis SigW bound to the -35 promoter element is reported and it is revealed that DNA recognition and anti-sigma factor binding of SigW are mutually exclusive.

Structural insights into the regulation of Bacillus subtilis SigW activity by anti-sigma RsiW

The crystal structures of SigW in complex with the cytoplasmic domain of RsiW and compared the conformation of the CHCC motif in the reduced/zinc binding and the oxidized states revealed that £iW inhibits the promoter binding of Sigw by interacting with the surface groove of Sig W.

Group 3 sigma factors in the marine cyanobacterium Synechococcus sp. strain PCC 7002 are required for growth at low temperature.

Since SigG and SapG interact in yeast cells and the sigG and sapG mutants showed a similar growth phenotype, SapG is likely to be a regulatory protein for SigG involved in the same pathway in transcriptional regulation in this cyanobacterium.

Crystal structure of Escherichia coli sigmaE with the cytoplasmic domain of its anti-sigma RseA.

The 2 A resolution crystal structure of the Escherichia coli ECF sigma factor sigma(E) in an inhibitory complex with the cytoplasmic domain of its anti-sigma, RseA, reveals that RSEA functions by sterically occluding the two primary binding determinants on sigma (E) for core RNA polymerase.

Promoter recognition by Bacillus subtilis sigmaW: autoregulation and partial overlap with the sigmaX regulon.

It is reported that sigW mutants have elevated transcription of some sigmaX-controlled genes, and the converse is also true: in a sigX mutant, PW is derepressed during logarithmic growth, suggesting that these two regulons are mutually antagonistic.

Organization and expression of the Bacillus subtilis sigY operon.

The organization and function of the sigY operon are significantly conserved in several microorganisms living in adverse living environments, and its transcription is likely to be directed by sigmaY, a member of the extracytoplasmic function (ECF) family of sigma factors.

Sequence of the Bacillus subtilis genome region in the vicinity of the lev operon reveals two new extracytoplasmic function RNA polymerase sigma factors SigV and SigZ.

It is demonstrated that the sigY operon is expressed from an autoregulatory promoter site, P(Y), which was supported by analysis of direct targets for sigma(Y) transcription with whole-genome runoff transcription followed by macroarray analysis.
