Modification methylase NgoPII

Gene

ngoPIIM

Organism
Neisseria gonorrhoeae
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

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

Catalytic activityi

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