The DNA sequence spanning coordinates 9.9 to 16.4 kilobases of the lactose transposon Tn951 ( Cornelis et al., Mol. Gen. Genet. 160:215-224, 1978) constitutes a transposable element by itself. Unlike Tn951 ( Cornelis et al., Mol. Gen. Genet. 184:241-248, 1981), this element, called Tn2501 , transposes in the absence of any other transposon. Transposition of Tn2501 proceeds through transient cointegration and duplicates 5 base pairs of host DNA. Tn2501 is flanked by nearly perfect inverted repeats (44 of 48), related to the inverted repeats of Tn21 ( Zheng et al., Nucleic Acids Res. 9:6265-6278, 1982). Unlike Tn21 , Tn2501 does not confer mercury resistance.
乳糖转座子Tn951(科内利斯等人,《分子与普通遗传学》160:215 - 224,1978年)中跨度为9.9至16.4千碱基的DNA序列本身构成一个转座元件。与Tn951(科内利斯等人,《分子与普通遗传学》184:241 - 248,1981年)不同,这个名为Tn2501的元件在没有任何其他转座子的情况下进行转座。Tn2501的转座通过瞬时共整合进行,并复制宿主DNA的5个碱基对。Tn2501两侧是近乎完美的反向重复序列(48个中的44个),与Tn21的反向重复序列相关(郑等人,《核酸研究》9:6265 - 6278,1982年)。与Tn21不同,Tn2501不赋予汞抗性。
