Norepinephrine 119-133 catechol-O-methyltransferase Homo sapiens 64-92 17201629-5 2006 Knowledge about thermogenesis-induced weight loss produced by green tea"s epigallocatechin gallate and its ability to inhibit catechol-O-methyltransferase is important for health benefits and for prolonging the action of norepinephrine in the synaptic cleft. Norepinephrine 221-235 catechol-O-methyltransferase Homo sapiens 126-154
