Species: Rattus norvegicus
The approximate molecular weight was determined by sedimentation analysis in a sucrose gradient [Simon78]. The predicted amino acid sequence showed 88.3% homology with the mouse sequence and 64.2% with the human sequence. A putative catalytic domain showed 93.8% homology with the mouse sequence and 89.5% with the human sequence [Kimura98].

Enzymatic reaction of: DNA (cytosine-5) methyltransferase
EC Number: 188.8.131.52
The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.
The reaction is physiologically favored in the direction shown.
The enzyme partially purified from rat liver specifically produced 5-methylcytosine. The other product, S-adenosyl -homocysteine, competitively inhibited the reaction with a Ki of 0.33 μM [Simon78].
