title: A type II restriction endonuclease with an eight nucleotide specificity from Streptomyces fimbriatus.
abstract: A new site-specific endonuclease, Sfi I, has been isolated from Streptomyces fimbriatus . This is the first report of a type II restriction endonuclease whose recognition specificity requires eight nucleotides. Sfi I cleaves the sequence, GGCCNNNN / NGGCC , symmetrically to produce a three base, 3' extension.
