Protein

Modification methylase AbrI

Gene
abrIM
Organism
Azospirillum brasilense
Status
Reviewed - Annotation score: 2 out of 5 - Protein inferred from homologyi

Functioni

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

Catalytic activityi

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