Modification methylase BbvI

Gene

bbvIM

Organism
Brevibacillus brevis (Bacillus brevis)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

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

Catalytic activityi

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