PROSITE documentation PDOC01011Flagellar motor protein motA family signature
Description
The bacterial protein motA [1] is required for the rotation of the flagellar motor. This protein probably forms a transmembrane proton channel used to energize the flagellar rotary motor. The motA protein is an integral membrane protein that contains four transmembrane domains.
As as signature for the motA family of proteins, we selected a conserved region that corresponds to the fourth transmembrane region.
