Protein

Modification methylase SsoII

Gene

ssoIIM

Organism
Shigella sonnei
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

This methylase recognizes the double-stranded sequence CCNGG, causes specific methylation on C-2 on both strands, and protects the DNA from cleavage by the SsoII endonuclease.

Catalytic activityi

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