diamine oxidaseAmine oxidase (copper-containing), EC 22.214.171.124. This enzyme was deleted as it was classified based on cofactor content rather than reaction catalysed; it is now known to contain two distinct enzyme activities, and thus has been replaced by two enzymes: EC 126.96.36.199 (primary-amine oxidase) and EC 188.8.131.52 (diamine oxidase).
