Protein

Modification methylase HgiBI

Gene

hgiBIM

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 GGWCC, causes specific methylation on C-? on both strands, and protects the DNA from cleavage by the HgiBI endonuclease.

Catalytic activityi

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