WebAbstract. Norepinephrine (NE) and epinephrine (E) are metabolized extraneuronally by catechol-O-methyl-transferase to the metanephrines (MNs), normetanephrine (NMN) and metanephrine (MN). Subjects in this study received infusions of tritium-labeled NE and E. Concentrations of MNs and catecholamines were measured in plasma flowing into and … WebXorepinephrine is metabolized in an analogous manner. Figure 1 shows the pathway for the metabolism of the catecholamines. An enzyme, catechol-O-methyl transferase, that O-methylates catecholamines and other catechols has been described.1 S-adenosyl1 - inethionine serves as the methyl donor for this reaction. Catechol-O-methyl transferase was
