A nonswarming Serratia liquefaciens mutant deficient in serrawettin W2 production was constructed by transposon mutagenesis. Sequence homology indicated that insertion had occurred in gene swrA, which encodes a putative peptide synthetase. Expression of swrA is controlled by quorum sensing.
通过转座子诱变构建了一株不产生灵菌红素W2且不扩散的液化沙雷氏菌突变体。序列同源性表明插入发生在swrA基因中,该基因编码一种假定的肽合成酶。swrA的表达受群体感应控制。
