Tyramine hydrochloride, benzylamine hydrochloride, amine oxidase inhibitors, quercetin, trans-resveratrol, and other reagents were obtained from Sigma-Aldrich (Saint-Quentin-Fallavier, France), except otherwise specified.
However, resveratrol and other phenolic compounds altered the consequences of amine oxidase activities that rely on hydrogen peroxide production in hAT, since they were impairing the insulin-like action of benzylamine on glucose uptake in adipocytes.

Some of the members of this class of cuproenzymes include Cu/Zn SOD (antioxidant defense), cytochrome C oxidase (mitochondrial respiration), CP (iron metabolism), tyrosinase (pigmentation), lysyl oxidase (collagen maturation in connective tissue), Hephaestin (intestinal iron efflux), dopamine [[beta]-hydroxylase (catecholamine synthesis), Peptidylglycine [alpha] -amidating monooxygenase (peptide-hormone processing), amine oxidase (removal of hormones), ascorbate oxidase and catalase oxidase (oxidation of primary alcohols to aldehydes) (44).
Pea seedlings amine oxidase (PSAO) has been found to have a 100% relative specific activity towards 1,4-diaminobutane, 111% towards 1,5-diaminopentane, 56% towards agmatine and spermidine, 44% towards 1,6-diaminohexane, 30% towards histamine, 8% towards spermine, and no activity towards 1,3-diaminopropane [13].
Studying a bovine amine oxidase, two independent research groups found clues that pyrroloquinoline quinone (PQQ) might be the enzyme's missing sidekick in cows -- and perhaps in humans as well, Klinman says.
Cytochromes P450 receive particular attention, namely their multiplicity, structure, catalytic mechanisms, and the various reactions they catalyze, while other oxidoreductases are also presented, such as flavin monooxygenases, monoamine oxidases and other amine oxidases, aldehyde oxidase and xanthine dehydrogenase, peroxidases, and dehydrogenases-reductases.
