motB

Gene
motB
Protein
Motility protein B
Organism
Salmonella typhimurium (strain LT2 / SGSC1412 / ATCC 700720)
Length
309 amino acids
Function
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).
Similarity
Belongs to the MotB family.

Protein
Motility protein B
Organism
Escherichia coli (strain K12)
Length
308 amino acids
Function
MotA and MotB comprise the stator element of the flagellar motor complex. Required for the rotation of the flagellar motor. Probably a linker that fastens the torque-generating machinery to the cell wall. Overexpression of this protein with MotA improves 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 MotB family.
