A small-colony forming variant of Escherichia coli with a mutation in the ncf gene was analysed. The alternation of the protein composition in the cytoplasmic membrane and the interaction with K and E group colicins indicated a membrane mutation. The effect of this mutation on some membrane-bound processes, the activity of Mg2+-activated ATPase, the growth on different carbon sources and the active transport of amino acids, is described. This mutation does not exert any effect on the electron transport system.
对一株ncf基因突变的大肠杆菌小菌落形成变体进行了分析。细胞质膜中蛋白质组成的变化以及与K和E群大肠杆菌素的相互作用表明存在膜突变。描述了这种突变对一些膜结合过程、Mg2+激活的ATP酶活性、在不同碳源上的生长以及氨基酸主动转运的影响。这种突变对电子传递系统没有任何影响。
