EZ-Tn5™ Transposase* is a hyperactive, muta ted form of Tn5 transposase and a highly efficient enzyme for insertion of an EZ-Tn5 Trans poson into any target DNA, in vitro.In addition to EZ-Tn5 Transposase, efficient transposition requires that each EZ-Tn5 Transposon have a specific 19-bp transposase recognition se quence (Mosaic End or ME sequence) at each of its ends. Mutations engineered into both the 19-bp MEs and the EZ-Tn5 Transposase results in an in vitro transposition frequency that is 1000-fold greater than wild type.
EZ-Tn5 Transposase catalyzes a multi-step “cut and paste” transposition reaction. Initially, the enzyme binds the 19-bp ME of the transposon to form a Transposome™(synaptic complex). The transposome then randomly attacks and cleaves the phosphodiester backbone of the target DNA. Finally, the EZ-Tn5 Transposase catalyzes the covalent linkage of the 3′-OH ends of the transposon to the exposed 5′-phos phorylated ends of the target DNA. Transposi tion creates a 9-bp sequence duplication imme diately flanking the transposon insertion site.
EZ-Tn5™转座酶是一种高活性,突变形式的Tn5转座酶,是一种在体外将EZ-Tn5转座子插入任何靶标DNA的高效酶。除EZ-Tn5转座酶外,高效的转座还要求每个EZ-Tn5转座子在其每个末端均具有特定的19 bp转座酶识别序列(Mosaic End或ME序列)。工程化到19 bp的ME和EZ-Tn5转座酶中的突变产生的体外转座频率是野生型的1000倍。
EZ-Tn5转座酶催化一个多步骤的“剪切和粘贴”转座反应。 最初,该酶结合转座子的19 bp ME形成Transposome™(突触复合体)。 然后该转座体随机攻击并切割靶DNA的磷酸二酯主链。 最后,EZ-Tn5转座酶催化转座子的3'-OH末端与目标DNA暴露的5'-磷酸化末端的共价键。 转座可立即形成位于转座子插入位点侧翼的9 bp序列重复。
