Protein

DNA adenine methylase

Gene

DAM

Organism
Enterobacteria phage T2 (Bacteriophage T2)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

This methylase recognizes the double-stranded sequence GATC, causes specific methylation on A-2 on both strands.

Catalytic activityi

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