Two F- mutants deficient in conjugation with F-type donors are isolated and characterized. Phenotypically, these mutants are similar; they have heptose-less lipopolysaccharide and lack some outer membrane protein. Genotypically, they are different. One mutant harbors a point mutation in the 70 to 74 min region, while the other is deleted for the chromosomal region 6.5 to 8.5 min. Comparison of the properties of the conjugation-deficient mutants described in this paper with other such mutants suggests that an outer membrane protein is the receptor for the f-pilus.
分离并鉴定了两个与F型供体结合缺陷的F-突变体。从表型上看，这些突变体相似；它们具有无庚糖的脂多糖且缺乏一些外膜蛋白。从基因型上看，它们不同。一个突变体在70至74分钟区域存在点突变，而另一个在染色体6.5至8.5分钟区域缺失。将本文所述的结合缺陷型突变体的特性与其他此类突变体进行比较表明，一种外膜蛋白是F菌毛的受体。
