Dsh. Shah et al., RHODOBACTER-SPHAEROIDES WS8 EXPRESSES A POLYPEPTIDE THAT IS SIMILAR TO MOTB OF ESCHERICHIA-COLI, Journal of bacteriology, 177(10), 1995, pp. 2929-2932
A gene which complements a paralyzed flagellar mutant of Rhodobacter s
phaeroides was sequenced. The derived protein sequence has similarity
to MotB. R. sphaeroides MotB lacks the C-terminal peptidoglycan-bindin
g motif of other MotB proteins. This divergence of sequence may reflec
t the unusual, unidirectional, stop-start action of the R. sphaeroides
flagellar motor.
