ScrFI: a new sequence–specific endonuclease fromStreptococcus cremoris

Abstract
A novel sequence–specific endonuclease has been isolated from Streptococcus cremoris F. ScrFI recognises the sequence: 5‘CC↓NGG3’ 3‘GGN↑CC5’ and cleaves as indicated by the arrow ↓. It is the first enzyme to recognise this sequence and the first endonuclease reported from the lactic streptococci used in dairy fermentations.
