Protein
Motility protein A
Organism
Escherichia coli (strain K12)
Function
MotA and MotB comprise the stator element of the flagellar motor complex. Required for rotation of the flagellar motor. Probable transmembrane proton channel. Overexpression of MotA, with or without MotB, restores motility in a pdeH disruption, (a c-di-GMP phosphodiesterase) suggesting there is an interaction (direct or indirect) between the c-di-GMP-binding flagellar brake protein YcgR and the flagellar stator.
Similarity
Belongs to the MotA family.
