- FunctionsDNA binding / N-methyltransferase activity / site-specific DNA-methyltransferase (adenine-specific) activityProcessesDNA restriction-modification system
- General Function
- Site-specific dna-methyltransferase (adenine-specific) activity
- Specific Function
- This methylase recognizes the double-stranded sequence GAATTC, causes specific methylation on A-? on both strands, and protects the DNA from cleavage by the RsrI endonuclease.
