Bacterial flagellar motor

Y Sowa, RM Berry - Quarterly reviews of biophysics, 2008 - cambridge.org
The bacterial flagellar motor is a reversible rotary nano-machine, about 45 nm in diameter,
embedded in the bacterial cell envelope. It is powered by the flux of H+ or Na+ ions across …

Flagellar motility in bacteria: structure and function of flagellar motor

H Terashima, S Kojima, M Homma - … review of cell and molecular biology, 2008 - Elsevier
Bacterial flagella are filamentous organelles that drive cell locomotion. They thrust cells in
liquids (swimming) or on surfaces (swarming) so that cells can move toward favorable …

Load-dependent assembly of the bacterial flagellar motor

MJ Tipping, NJ Delalez, R Lim, RM Berry, JP Armitage - MBio, 2013 - Am Soc Microbiol
It is becoming clear that the bacterial flagellar motor output is important not only for bacterial

N Takekawa, K Imada, M Homma - Trends in microbiology, 2020 - cell.com
Many bacteria swim by means of flagella that are rotated by a nanoscale motor embedded in
the cell membrane. Torque is generated by the interaction between ion-conducting …

A molecular brake, not a clutch, stops the Rhodobacter sphaeroides flagellar motor

T Pilizota, MT Brown, MC Leake… - Proceedings of the …, 2009 - National Acad Sciences
