An endonuclease from Chlamydomonas reinhardtii that cleaves the sequence TATA
R Sklar, D Altman and R Sager
An endodeoxyribonuclease, designated CreI, was purified 16,000-fold from
zygotes of the eukaryote Chlamydomonas reinhardtii. CreI preferentially
attacks the sequence TATA producing double strand breaks with
3'-phosphomonoester and 5'-hydroxyl termini. The endonuclease has an Mr =
27,000 and requires Ca2+ at pH 7.5 for optimal activity.
