Colicin biology.
Cascales E, Buchanan SK, Duché D, Kleanthous C, Lloubès R, Postle K, Riley M, Slatin S, Cavard D. Cascales E, et al. Microbiol Mol Biol Rev. 2007 Mar;71(1):158-229. doi: 10.1128/MMBR.00036-06. Microbiol Mol Biol Rev. 2007. PMID: 17347522 Free PMC article. Review.
Colicins are proteins produced by and toxic for some strains of Escherichia coli. ...The structures of some colicins are known at the atomic level and are discussed. Colicins exert their lethal action by first binding to specific receptors, which are outer me …

Colicin E1 opens its hinge to plug TolC.
Budiardjo SJ, Stevens JJ, Calkins AL, Ikujuni AP, Wimalasena VK, Firlar E, Case DA, Biteen JS, Kaelber JT, Slusky JSG. Budiardjo SJ, et al. Elife. 2022 Feb 24;11:e73297. doi: 10.7554/eLife.73297. Elife. 2022. PMID: 35199644 Free PMC article.
Here, we capture the colicin E1 translocation domain inside its membrane receptor, TolC, by high-resolution cryo-electron microscopy to obtain the first reported structure of a bacteriocin bound to TolC. Colicin E1 binds stably to TolC as an open hinge through the T …

Colicin U from Shigella boydii Forms Voltage-Dependent Pores.
Dolejšová T, Sokol A, Bosák J, Šmajs D, Konopásek I, Mikušová G, Fišer R. Dolejšová T, et al. J Bacteriol. 2019 Nov 20;201(24):e00493-19. doi: 10.1128/JB.00493-19. Print 2019 Dec 15. J Bacteriol. 2019. PMID: 31548276 Free PMC article.
In agreement with the high degree of homology between their C-terminal domains, colicin U shares some pore characteristics with the related colicins A and B. ...However, in contrast to related colicins, we observed a very low cationic selectivity of colici …

Colicin translocation across the Escherichia coli outer membrane.
Housden NG, Kleanthous C. Housden NG, et al. Biochem Soc Trans. 2012 Dec 1;40(6):1475-9. doi: 10.1042/BST20120255. Biochem Soc Trans. 2012. PMID: 23176501 Review.
Our work focuses on the import mechanism of the group A endonuclease (DNase) colicin ColE9 into Escherichia coli, where we combine in vivo observations with structural, biochemical and biophysical approaches to dissect the molecular mechanism of colicin entry. ...In …
