A novel gene conferring resistance to picromycin in Streptomyces and related organisms was cloned from a genomic library of Streptomyces felleus DNA. The novel picromycin resistance-conferring gene can be isolated on an ∼2.8 kb PvuII fragment by subcloning the restriction fragment from plasmid pOJ321. This PvuII fragment contains all of the information required for the expression of the picromycin resistant phenotype in Streptomyces. Methods for inducing resistance, as well as vectors and transformants containing the novel picromycin resistance gene, are provided.
从费氏链霉菌 DNA 的基因组文库中克隆出了链霉菌及相关生物抗短波霉素的新型基因。通过从质粒 pOJ321 中亚克隆限制性片段,可在一个 ∼ 2.8 kb 的 PvuII 片段上分离出新的耐短链霉素基因。该 PvuII 片段包含在链霉菌中表达抗吡咯霉素表型所需的全部信息。本文提供了诱导抗性的方法,以及含有新型耐苦参碱基因的载体和转化体。
