Protein

Modification methylase CviRI

Gene

CVIRIM

Organism
Paramecium bursaria Chlorella virus XZ-6E (PBCV-XZ-6E)
Status
Reviewed - Annotation score: 2 out of 5- Protein inferred from homologyi

Functioni

This methylase recognizes the double-stranded sequence TGCA, causes specific methylation on A-4 on both strands, and protects the DNA from cleavage by the CviRI endonuclease.

Catalytic activityi

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