Oceanobacillus iheyensis (strain DSM 14371 / JCM 11309 / KCTC 3954 / HTE831) [Complete proteome] [HAMAP]

Taxonomic identifier

221109 [NCBI]

Taxonomic lineage

Bacteria › Firmicutes › Bacillales › Bacillaceae › Oceanobacillus

Protein attributes

Sequence length	460 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	This methylase recognizes the double-stranded sequence ACCGGT, causes specific methylation on C-? on both strands, and protects the DNA from cleavage by a specific endonuclease Potential.
Catalytic activity	S-adenosyl-L-methionine + DNA = S-adenosyl-L-homocysteine + DNA containing 5-methylcytosine.
Sequence similarities	Belongs to the C5-methyltransferase family.
