ScrFI: a new sequence–specific endonuclease from<i>Streptococcus cremoris</i>

Abstract

A novel sequence-specific endonuclease has been isolated from Streptococcus cremoris F. ScrFI recognises the sequence: (formula; see text) 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.
