Notes:
ATP is required for DNA cleavage. Efficient cleavage requires the presence of two inversely oriented recognition sites. A head to head orientation is preferred. The "head" of the sequence is defined as the dG at the 3??end of the CAGCAG strand (top strand). Cleavage efficiency is also affected by the distance between the two sites.EcoP15I requires two copies of its recognition sequence for cleavage tooccur, with limited cleavage on plasmids with a single site.Based on the st
