Motility protein B

Gene

motB

Organism
Salmonella typhimurium (strain LT2 / SGSC1412 / ATCC 700720)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-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

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
