A gene which complements a paralyzed flagellar mutant of Rhodobacter sphaeroides was sequenced. The derived protein sequence has similarity to MotB. R. sphaeroides MotB lacks the C-terminal peptidoglycan-binding motif of other MotB proteins. This divergence of sequence may reflect the unusual, unidirectional, stop-start action of the R. sphaeroides flagellar motor.
对一个能互补球形红细菌鞭毛麻痹突变体的基因进行了测序。推导的蛋白质序列与MotB具有相似性。球形红细菌MotB缺乏其他MotB蛋白的C端肽聚糖结合基序。这种序列差异可能反映了球形红细菌鞭毛马达不同寻常的、单向的、启停动作。
