亲,我想请教下,这个酶要哪里买得到。还有识别位点有那些呀?是不是要完整的识别位点存在才会剪切呢?(比如说..CCTCAGC...和.GGAGT(cut site)CG这个只有完整的时候才切割还是存在TCG就会切割呢?)我是新手。再次感谢!

Abstract—Nicking endonucleases are a new type of enzymes. Like restriction endonucleases, they recognize short specific DNA sequence and cleave DNA at a fixed position relatively to the recognition sequence. However, unlike restriction
endonucleases, nicking endonucleases cleave only one predetermined DNA strand. Until recently, nicking endonucleases were suggested to be naturally mutated restriction endonucleases which had lost their ability to dimerize and as a result the ability to cleave the second strand.
