Modification methylase CcrMI

Gene

ccrMIM

Organism
Caulobacter crescentus (strain NA1000 / CB15N)
Status
Reviewed-Annotation score: 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.
