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?轉(zhuǎn)座酶是一種高活性，突變形式的Tn5轉(zhuǎn)座酶，是一種在體外將EZ-Tn5轉(zhuǎn)座子插入任何靶標(biāo)DNA的高效酶。除EZ-Tn5轉(zhuǎn)座酶外，高效的轉(zhuǎn)座還要求每個EZ-Tn5轉(zhuǎn)座子在其每個末端均具有特定的19 bp轉(zhuǎn)座酶識別序列（Mosaic End或ME序列）。工程化到19 bp的ME和EZ-Tn5轉(zhuǎn)座酶中的突變產(chǎn)生的體外轉(zhuǎn)座頻率是野生型的1000倍。
EZ-Tn5轉(zhuǎn)座酶催化一個多步驟的“剪切和粘貼”轉(zhuǎn)座反應(yīng)。 最初，該酶結(jié)合轉(zhuǎn)座子的19 bp ME形成Transposome?（突觸復(fù)合體）。 然后該轉(zhuǎn)座體隨機(jī)攻擊并切割靶DNA的磷酸二酯主鏈。 最后，EZ-Tn5轉(zhuǎn)座酶催化轉(zhuǎn)座子的3'-OH末端與目標(biāo)DNA暴露的5'-磷酸化末端的共價(jià)鍵。 轉(zhuǎn)座可立即形成位于轉(zhuǎn)座子插入位點(diǎn)側(cè)翼的9 bp序列重復(fù)。
