* Flagellar motor protein motA family signature *
*************************************************

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.

-Consensus pattern: A-[LMF]-x-[GAT]-T-[LIVMF]-x-G-x-[LIVMF]-x(7)-P
-Sequences known to belong to this class detected by the pattern: ALL.
-Other sequence(s) detected in Swiss-Prot: NONE.
-Last update: July 1999 / Pattern and text revised.
