Three mutations caused by the integration of IS4 in galT in both possible orientations were shown by DNA sequence analysis to be integrated between a duplication of eleven base pairs of gene galT. IS4 has been cloned from its single position on the E. coli K12 chromosome. Here, 12 base pairs are duplicated adjacent to IS4. This sequence is unrelated to the duplicated sequence in galT.
DNA序列分析表明,由IS4以两种可能的方向整合到galT中所引起的三个突变,被整合在galT基因11个碱基对的重复序列之间。IS4已从其在大肠杆菌K12染色体上的单一位置克隆出来。在这里,12个碱基对在IS4相邻处发生重复。该序列与galT中的重复序列无关。
