Protein

Modification methylase MthTI

Gene

mthTIM

Organism
Methanothermobacter thermautotrophicus (Methanobacterium thermoformicicum)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

This methylase recognizes the double-stranded sequence GGCC, causes specific methylation on C-3 on both strands, and protects the DNA from cleavage by the MthTI endonuclease.1 Publication

Catalytic activityi

S-adenosyl-L-methionine + DNA = S-adenosyl-L-homocysteine + DNA containing 5-methylcytosine.1 Publication
