Protein

Modification methylase SmeI

Gene
smeIM, ccrM, R00926, SMc00021
Organism
Rhizobium meliloti (strain 1021) (Ensifer meliloti) (Sinorhizobium meliloti)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

This methylase recognizes the double-stranded sequence GANTC and causes specific methylation on A-2 on both strands. Ccrm-mediated methylation has important cellular functions. Appears to contribute to the accurate cell-cycle control of DNA replication and cellular morphology.

Catalytic activityi

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