Abstract
Flagella rotated exclusively counterclockwise in Escherichia coli cell envelopes prepared from wild-type cells, whose flagella rotated both clockwise and counterclockwise, from mutants rotating their flagella counterclockwise only, and even from mutants rotating their flagella primarily clockwise. Some factor needed for clockwise flagellar rotation appeared to be missing or defective in the cell envelopes.
摘要
在从野生型细胞制备的大肠杆菌细胞膜中，鞭毛仅逆时针旋转，野生型细胞的鞭毛可顺时针和逆时针旋转，来自仅逆时针旋转鞭毛的突变体，甚至来自主要顺时针旋转鞭毛的突变体。顺时针鞭毛旋转所需的某些因素似乎在细胞膜中缺失或有缺陷。
