1. BspMI requires two copies of its recognition sequence for cleavage to occur. Thus, the single BspMI sites in pBR322 and pUC18 and 19 are resistant to cleavage. A 100-fold overdigestion cuts less than half of the DNA.
2. BfuAI is an isoschizomer of BspMI.
3. Sites in some plasmid DNAs that are resistant to cleavage by BspMI may be cleaved by BfuAI.
4. May exhibit star activity in NEBuffer r2.1.
5. Requires two or more sites for cleavage. Please review the enzyme list and recommendations in the following table as well as the background information article.
6. Not sensitive to CpG, dcm, or dam methylation.
