Bacterial sigma factors: a historical, structural, and genomic perspective.
Feklístov A, Sharon BD, Darst SA, Gross CA. Feklístov A, et al. Annu Rev Microbiol. 2014;68:357-76. doi: 10.1146/annurev-micro-092412-155737. Epub 2014 Jun 18. Annu Rev Microbiol. 2014. PMID: 25002089 Review.
Transcription initiation is the crucial focal point of gene expression in prokaryotes. The key players in this process, sigma factors (sigmas), associate with the catalytic core RNA polymerase to guide it through the essential steps of initiation: promoter recogniti …

Stragier P. Stragier P. EMBO J. 1991 Dec;10(12):3559-66. doi: 10.1002/j.1460-2075.1991.tb04922.x. EMBO J. 1991. PMID: 1935888 Free PMC article. Review. No abstract available.
Periplasmic stress and ECF sigma factors.
Raivio TL, Silhavy TJ. Raivio TL, et al. Annu Rev Microbiol. 2001;55:591-624. doi: 10.1146/annurev.micro.55.1.591. Annu Rev Microbiol. 2001. PMID: 11544368 Review.
Many of these responses are controlled by extracytoplasmic function (ECF) sigma factors that respond to external signals by means of a membrane-localized anti-sigma factor. One of the best-characterized, ECF-regulated responses is the sigma(E) envelope stress …

A snapshot of the λ T4rII exclusion (Rex) phenotype in Escherichia coli.
Wong S, Alattas H, Slavcev RA. Wong S, et al. Curr Genet. 2021 Oct;67(5):739-745. doi: 10.1007/s00294-021-01183-2. Epub 2021 Apr 20. Curr Genet. 2021. PMID: 33877398 Review.
For the first time, key host proteins have recently been linked to Rex, including sigma(E), sigma(S), TolA, and other membrane proteins. Together with the known Rex system components, the RII proteins of bacteriophage T4 and the Rex proteins from bacteriophage lambd …
