IUBMB Enzyme Nomenclature


Accepted name: aralkylamine dehydrogenase (azurin)

Reaction: ArCH2NH2 + H2O + 2 azurin = ArCHO + NH3 + 2 reduced azurin

Glossary: azurin = an electron-transfer protein containing a type-1 copper site

Other name(s): aromatic amine dehydrogenase; arylamine dehydrogenase; tyramine dehydrogenase; aralkylamine:(acceptor) oxidoreductase (deaminating)

Systematic name: aralkylamine:azurin oxidoreductase (deaminating)

Comments: Phenazine methosulfate can act as acceptor. Acts on aromatic amines and, more slowly, on some long-chain aliphatic amines, but not on methylamine or ethylamine
