Modification methylase MboIB

Gene

mboIBM

Organism
Moraxella bovis
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

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

Catalytic activityi

S-adenosyl-L-methionine + DNA adenine = S-adenosyl-L-homocysteine + DNA 6-methylaminopurine.
