Protein

Motility protein B

Gene

motB

Organism
Helicobacter pylori (strain ATCC 700392 / 26695) (Campylobacter pylori)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

MotA and MotB comprise the stator element of the flagellar motor complex. Required for the rotation of the flagellar motor. Might be a linker that fastens the torque-generating machinery to the cell wall (By similarity).By similarity

Interactioni

Subunit structurei

Each stator complex is composed of 4 MotA and 2 MotB subunits. 2 A subunits and 1 B subunit are thought to form a single ion channel, so that each stator complex contains two channels (By similarity).By similarity
