Protein
Modification methylase AluI
Gene
aluIM
Organism
Cellulosimicrobium cellulans (Arthrobacter luteus)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

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

Catalytic activityi

S-adenosyl-L-methionine + DNA = S-adenosyl-L-homocysteine + DNA containing 5-methylcytosine.
