Protein

Modification methylase EcoRI

Gene

ecoRIM

Organism
Escherichia coli
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

This methylase recognizes the double-stranded sequence GAATTC, causes specific methylation on A-3 on both strands, and protects the DNA from cleavage by the EcoRI endonuclease.

Catalytic activityi

S-adenosyl-L-methionine + DNA adenine = S-adenosyl-L-homocysteine + DNA 6-methylaminopurine.
