The rfb gene cluster of Salmonella typhimurium encodes the enzymes required for the biosynthesis of the O-Antigen. A part of it has been cloned in plasmid vectors pBR322 and pUC9 using an adjacent, previously cloned, part of the his operon (Barnes 1981) as a molecular probe for the first clone. A detailed restriction enzyme map of 7.57 kb of rfb DNA is presented and the approximate locations of two of the genes, rfbK and rfbM have been defined.
鼠伤寒沙门氏菌的rfb基因簇编码O抗原生物合成所需的酶。利用相邻的、先前已克隆的组氨酸操纵子的一部分(Barnes,1981年)作为第一个克隆的分子探针,已将其一部分克隆到质粒载体pBR322和pUC9中。给出了7.57 kb的rfb DNA的详细限制性酶切图谱,并确定了两个基因rfbK和rfbM的大致位置。
