A novel class-II restriction endonuclease designated SwaI was purified from Staphylococcus warneri. This enzyme cleaves adenovirus 2 DNA, SV40 DNA and M13mp7 at one site each, but does not cleave lambda, PhiX174, pBR322 or pBR328 DNA. SwaI recognizes the octanucleotide sequence 5'-ATTTAAAT-3', cleaving in the center of the recognition sequence creating blunt ended DNA fragments. SwaI was used to digest chromosomal DNA from various microorganisms and human cells.
一种名为SwaI的新型II类限制性内切酶是从沃氏葡萄球菌中纯化出来的。这种酶分别在腺病毒2 DNA、SV40 DNA和M13mp7的一个位点切割,但不切割λ噬菌体、PhiX174、pBR322或pBR328 DNA。SwaI识别八核苷酸序列5'-ATTTAAAT-3',在识别序列的中心进行切割,产生平端DNA片段。SwaI被用于消化来自各种微生物和人类细胞的染色体DNA。
