Amine oxidases (EC 1.4.3.6) from Aspergillus niger, AO-I (2 x 75 kDa) and AO-II (80 kDa), were examined to determine the cofactor structure. Inactivated with p-nitrophenylhydrazine, they showed absorption and fluorescence spectra similar to those published for other copper amine

Structural properties of dimeric (2 x 75 kDa) copper-containing amine oxidase (EC 1.4.3.6) from Aspergillus niger were studied. The enzyme treated with SDS was dissociated into subunits which showed different mobility on polyacrylamide gel without SDS. The separated subunits had

Quinohemoprotein amine dehydrogenase (QH-AmDH) catalyzes the oxidative deamination of aliphatic and aromatic amines. The enzyme from Pseudomonas putida has an alpha beta gamma heterotrimeric structure with two heme c groups in the largest alpha subunit, and a novel quinone cofactor

Resonance Raman spectroscopy is an excellent technique for providing structural information on the 2,4, 5-trihydroxyphenylalanine quinone (TPQ) cofactor in copper-containing amine oxidases. This technique has been used to investigate the copper- and O2-dependent biosynthesis of the TPQ cofactor in phenylethylamine

An improved purification scheme for an amine oxidase from equine plasma (EPAO), a nonruminant source, is described and the protein's active-site is characterized. EPAO is dimeric and contains one Type-2 Cu(II) ion per monomer. The EPAO Cu(II) site is spectroscopically
