STRUCTURE OF OXIDOREDUCTASE
Overview
The crystal structure of the complex between the copper amine oxidase from, Escherichia coli (ECAO) and a covalently bound inhibitor, 2-hydrazinopyridine, has been determined to a resolution of 2.0 A. The, inhibitor covalently binds at the 5 position of the quinone ring of the, cofactor, 2,4,5-trihydroxyphenylalaninequinone (TPQ). The inhibitor, complex is analogous to the substrate Schiff base formed during the, reaction with natural monoamine substrate. A proton is abstracted from a, methylene group adjacent to the amine group by a catalytic base during the, reaction. The inhibitor, however, has a nitrogen at this position, preventing proton abstraction and trapping the enzyme in a covalent, complex. The electron density shows this nitrogen is hydrogen bonded to, the side chain of ... [(full description)]
