Protein

Modification methylase AccI

Gene

accIM

Organism
Acinetobacter calcoaceticus
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

This methylase recognizes the double-stranded sequence GTMKAC, causes specific methylation on A-5 on both strands, and protects the DNA from cleavage by the AccI endonuclease.

Catalytic activityi

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