Good question....I know that Dopamine is broken down into norepinephrine by dopamine B-hydroxylase...and then norepinephrine is broken down into epinephrine by phenylethanolamine N-Methyltransferase. I do not know what breaks Epinephrine down.
Actually I just found an article about this....Looks like Epinephrine is broken down by catechol-O-methyl transferase into metanephrine.

Catechols (epinephrine and norepinephrine are catecholamines) are metabolized by MAO (Mono Amine Oxidase) and COMT (Catechol-O-Methyl Transferase). This can occur in either order; that is, MAO or COMT can work first.

NE is broken down by MAO in the vessicles and by COMT in the synaptic cleft.

Chris Johnson and Dave Williams asked the same question. You should read the answers side by side.
