We Isolated and characterized a new type II restriction endonuclease which recognizes the palindromic heptanucleotide sequence 5'-AGGWCCT-3' and cleaves double-stranded DNA after the first G in the sequence from a microorganism belonging to Steptomyces species. This enzyme cleaves adenovirus 2 DNA at eight sites, but does not cleave
phage, pBR322, pUC18 and 19, M13mp18 and 19, SV40, ColE1 and
X174 DNAs.
