Chain A,B   (FLIG_HELPY | O25119)
molecular function
    GO:0003774    motor activity    Catalysis of the generation of force resulting either in movement along a microfilament or microtubule, or in torque resulting in membrane scission, coupled to the hydrolysis of a nucleoside triphosphate.
biological process
    GO:0097588    archaeal or bacterial-type flagellum-dependent cell motility    Cell motility due to movement of bacterial- or archaeal-type flagella.
    GO:0071973    bacterial-type flagellum-dependent cell motility    Cell motility due to the motion of one or more bacterial-type flagella. A bacterial-type flagellum is a motor complex composed of an extracellular helical protein filament coupled to a rotary motor embedded in the cell envelope.
    GO:0071978    bacterial-type flagellum-dependent swarming motility    Bacterial-type flagellum-dependent cell motility in which the action of numerous flagella results in the smooth movement of a group of cells along a solid surface. Swarming motility is observed in groups of bacteria.
    GO:0006935    chemotaxis    The directed movement of a motile cell or organism, or the directed growth of a cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis).
cellular component
    GO:0009288    bacterial-type flagellum    A motor complex composed of an extracellular helical protein filament coupled to a rotary motor embedded in the cell envelope.
    GO:0009425    bacterial-type flagellum basal body    One of the three major substructures of the flagellin-based flagellum; a structure consisting of a rod, a series of rings, the Mot proteins, the switch complex and the flagellum-specific export apparatus. The rings anchor the flagellum to the cytoplasmic membrane (MS ring), the peptidoglycan (P ring) and the outer membrane (L ring). Examples of this component are found in bacteria.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
