Organism

Brucella suis [Complete proteome] [HAMAP]

Taxonomic identifier

29461 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Alphaproteobacteria › Rhizobiales › Brucellaceae › Brucella

Protein attributes

Sequence length	377 AA.
Sequence status	Complete.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	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 By similarity.
Catalytic activity	S-adenosyl-L-methionine + DNA adenine = S-adenosyl-L-homocysteine + DNA 6-methylaminopurine.
Sequence similarities	Belongs to the N(4)/N(6)-methyltransferase family.
