- These two proteins form pores that harvest energy for flagellar mechanical movement by proton motive force (PMF) across the membrane. (wikipedia.org)
- When the protons flow back into the cell through MotA and MotB along concentration and charge gradients, they release energy that is used for flagellar rotation. (wikipedia.org)
- The speed of the flagellar motor is dependent on the magnitude of the PMF acting on MotA and MotB. (wikipedia.org)
- Weak swarming motility and rare flagella were observed in a mutant deleted for FliI and for the non-flagellar type-III secretion ATPases InvJ and SsaN. (nature.com)
- These findings show that the flagellar secretion apparatus functions as a proton-driven protein exporter and that ATP hydrolysis is not essential for type III secretion. (nature.com)
- Dashed boxes indicate the proteins that function in flagellar secretion, either in the membrane-bound part of the apparatus or in delivery of substrate. (nature.com)
- The annotation of the full genome sequence revealed the absence of genes encoding for a non-flagellar type 3 protein secretion system (NF-T3SS). (assignster.com)

- The resulting mutation, obtained by conversion of a single amino acid residue (23rd Asp to Ala), resulted in malfunction of MotB, the motor switch protein of the flagellar machinery. (biomedcentral.com)
- C. jejuni does not possess classical virulence factors observed in bacterial enteropathogens such as enterotoxigenic Escherichia coli and Salmonella spp. (assignster.com)
- EF-G2's singular ability to sustain protein synthesis, albeit at slow rates, is crucial for bacterial gut colonization. (yale.edu)
- In this study, we evaluate the importance of motility on gut colonization by comparing motile and non-motile strains of Lactobacillus agilis in mice models. (biomedcentral.com)
- Motility and chemotactic ability likely confer advantages in gut colonization to L. agilis . (biomedcentral.com)
- It is obvious that motility is not essential for gut colonization, which raises the question of why the energy-consuming machinery is maintained, while in most other members it has been lost during evolution. (biomedcentral.com)
- Hence, in this study we hypothesize that the motility of these lactobacilli strains contributes to colonization in the gastrointestinal tract. (biomedcentral.com)
- CF27 exhibits a large number of genomic islands (mostly containing genes of unknown function), suggesting that a large number of genes has been acquired by horizontal gene transfer over time. (frontiersin.org)

- This mutant is flagellated but lacks motility due to malfunction of a motor-switch protein. (biomedcentral.com)
- A non-motile derivative of L. agilis BKN88, was constructed through replacement of the wild type motB gene with a mutant motB (Fig. 1a ). (biomedcentral.com)
- After sequence analysis confirmed the mutation of motB (D23A), the motility of the mutant strain, BKN134, was assessed in soft-agar culture. (biomedcentral.com)

- Lactobacilli are considered beneficial commensals in the gastrointestinal mucosa and are relatively well-studied except for the uncommon species which exhibit motility. (biomedcentral.com)
- FlgM inhibits transcription of its own gene, and so reduced FlgM export might partially reflect decreased cellular levels of the protein 9 . (nature.com)
- The motility parts collection is the culmination of our work on bacterial motility genes - MotA, MotB and FliC. (igem.org)
