Protein

Modification methylase NlaIV

Gene

nlaIVM

Organism
Neisseria lactamica
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

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

Catalytic activityi

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