Protein

Modification methylase HincII

Gene

hincIIM

Organism
Haemophilus influenzae
Status
Reviewed - Annotation score: 2 out of 5- Protein inferred from homologyi

Functioni

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

Catalytic activityi

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