1.A.30.1.7
The motor complex of the bacterial flagellum, MotAB. MotA is 295 aas long with about 5 putative TMSs in a 2 + 1 + 2 TMS arrangement, possibly with a C-terminal additional TMS. MotB is 309 aas long with a single N-terminal TMS. They comprise the stator element of the flagellar motor
complex and are required for rotation of the flagellar motor. Together they form the transmembrane proton channel. These two proteins are 94 and 91% identical to the E. coli complex (TC# 1.A.30.1.1) (Morimoto and Minamino 2014).
