WebT4 RNA Ligase 1 catalyzes the ligation of a 5' phosphoryl-terminated nucleic acid donor to a 3' hydroxyl-terminated nucleic acid acceptor through the formation of a 3' - 5' phosphodiester bond with hydrolysis of ATP to AMP and PPi. Substrates include single-stranded RNA and DNA as well as dinucleoside pyrophosphates. Webt4 dna连接酶可以修补双链dna、双链rna或dna/rna杂合链上的单链切口，使两个相邻的核苷酸连接起来，在dna修复和重组中起着重要的作用。 在传统的酶切酶连法载体构建过程中，T4 DNA连接酶可以搭配限制性内切酶一起完成酶切酶连实验。
Web利用t4 dna连接酶进行目的dna和载体的体外连接反应，也就是在双链dna 5’磷酸和相邻的3’羟基之间形成新的共价键。 如载体的两条链都带有5’磷酸（未脱磷），可形成4个新的磷酸二酯键；如载体DNA已脱磷，则只能形成2个新的磷酸二酯键，此时产生的重组DNA带有 ... http://img1.bioon.com/doc/showarticle.asp?newsid=112234
