A new type II restriction endonuclease AarI has been isolated from Arthrobacter aurescens SS2-322. AarI recognizes the non-palindromic heptanucleotide sequence 5'-CACCTGC(N)4/8-3' and makes a staggered cut at the fourth and eighth bases downstream of the target duplex producing a four base 5'-protruding end. AarI activity is stimulated by oligodeoxyribonucleotide duplexes containing an enzyme-specific recognition sequence.
一种新型II型限制性内切酶AarI已从金色节杆菌SS2-322中分离出来。AarI识别非回文七核苷酸序列5'-CACCTGC(N)4/8-3',并在靶双链下游的第四和第八个碱基处进行交错切割,产生一个四碱基的5'-突出末端。含有酶特异性识别序列的寡脱氧核糖核苷酸双链体可刺激AarI的活性。
