Descriptions Names[Advanced Search]

A motor complex composed of an extracellular helical protein filament coupled to a rotary motor embedded in the cell envelope. Any constituent part of a flagellum, a long whiplike or feathery structure borne either singly or in groups by the motile cells of many bacteria and unicellular eukaryotes and by the motile male gametes of many eukaryotic organisms, which propel the cell through a liquid medium. Any constituent part of flagellum, a 20 nm diameter filament composed of subunits of flagellin driven passively at its base by a motor powered by the transmembrane proton potential. Examples of this component are found in bacterial species. The portion of the flagellum that connects the filament to the basal body. Examples of this component are found in bacteria.
