Protein

Modification methylase TthHB8I

Gene

tthHB8IM

Organism
Thermus thermophilus (strain HB8 / ATCC 27634 / DSM 579)
Status
Reviewed - Annotation score: 2 out of 5- Protein inferred from homologyi

Functioni

This methylase recognizes the double-stranded sequence TCGA, causes specific methylation on A-4 on both strands and protects the DNA from cleavage by the TthHB8I endonuclease.

Catalytic activityi

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