Protein
Modification methylase HgiGI
Gene
hgiGIM
Organism
Herpetosiphon aurantiacus (Herpetosiphon giganteus)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

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

Catalytic activityi

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