The type II restriction enzymes prepared some years later had the very desirable property of cutting DNA into defined pieces and became the backbone of the genetic engineering revolution. In contrast, the type I

目前常用的载体构建系统有:基于TypeII型限制性内切酶的载体构建系统、基于TypeIIs型限制性内切酶的Golden Gate载体构建系统。 与基于TypeII型限制性内切酶的载体构建系统不同,Golden Gate载体构建方法,可实现在单一管内同时进行酶切和连接反应,不需要进行凝胶纯化及分步的酶切、连接反应,大大缩短实验时间,并且重组克隆不会...

Type I restriction–modification (R–M) systems are widespread in prokaryotic genomes and provide robust protection against foreign DNA. They are multisubunit enzymes with methyltransferase, endonuclease and translocase activities. Despite extensive studies over the past five decades, little is known about...
We have developed a protocol to assemble in one step and one tube at least nine separate DNA fragments together into an acceptor vector, with 90% of recombinant clones obtained containing the desired construct. This protocol is based on the use of type IIs restriction enzymes and is performed ...
(type II-Cas9 and type V-Cas12)13, have been adopted as eukaryotic genome editing tools. In contrast, the most abundant and diverse CRISPR-Cas systems belong to class 114. These systems, defined as type I and III, encode multi-subunit complex effectors13,14. In the case of type Is, ...

The present invention relates to a new Type II restriction endonuclease, Asc I, obtainable from Arthrobacter species, and to the process for producing the same. Restriction endonucleases are a class of enzymes that occur naturally in bacteria. When they are purified away from other contaminating bac...
