'''Crystal structure of copper amine oxidase from Arthrobacter globiformis: Holo form generated by biogenesis in crystal.'''<br />


==Overview==
==Crystal structure of copper amine oxidase from Arthrobacter globiformis: Holo form generated by biogenesis in crystal.==
The quinone cofactor TPQ in copper amine oxidase is generated by, posttranslational modification of an active site tyrosine residue. Using, X-ray crystallography, we have probed the copper-dependent autooxidation, process of TPQ in the enzyme from Arthrobacter globiformis. Apo enzyme, crystals were anaerobically soaked with copper; the structure determined, from this crystal provides a view of the initial state: the unmodified, tyrosine coordinated to the bound copper. Exposure of the copper-bound, crystals to oxygen led to the formation of freeze-trapped intermediates;, structural analyses indicate that these intermediates contain, dihydroxyphenylalanine quinone and trihydroxyphenylalanine. These are the, first visualized intermediates during TPQ biogenesis in copper amine, oxidase.
