Protein

Modification methylase BabI

Gene

ccrM

Organism
Brucella abortus (strain 2308)
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. Essential for viability.

Catalytic activityi

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