Protein

Modification methylase CeqI

Gene

ceqIM

Organism
Rhodococcus hoagii (Corynebacterium equii)
Status
Reviewed - Annotation score: 2 out of 5- Protein inferred from homologyi

Functioni

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

Catalytic activityi

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