Abstract
Studies have been made on the specificity of the methyl donor requirement of a betaine-homocysteine-methyl-transferase purified from pig liver. It was found that a number of betaine derivatives and sulfonium compounds could replace betaine as methyl donor. No evidence was obtained for ethyl group transfer. Many of the ammonium compounds tested as methyl donors interfered with the utilization of betaine, and betaine itself decreased the rate of methyl transfer from certain sulfonium compounds. The data presented are tentatively interpreted and discussed.
