Protein

Modification methylase PspPI

Gene
pspPIM
Organism
Psychrobacter sp. (strain TA137)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

This methylase recognizes the double-stranded sequence GGNCC, causes specific methylation on C-4 on both strands, and protects the DNA from cleavage by the PspPI endonuclease.

Catalytic activityi

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