Two DNA methyltransferases from murine erythroleukemia cells: purification, sequence specificity, and mode of interaction with DNA.


Dye-ligand chromatography on Cibacron blue F3GA-agarose has been used to resolve two species of DNA (cytosine-5-)-methyltransferase from nuclear extracts of uninduced Friend murine erythroleukemia cells. Each species has been highly purified; the activities in the first and second peaks were associated with polypeptides of Mr 150,000 and 175,000… (More)
