AGAO IN COMPLEX WITH RUTHENIUM-C4-WIRE AT 1.73 ANGSTROMS

OverviewOverview

Molecular wires comprising a Ru(II)- or Re(I)-complex head group, an, aromatic tail group, and an alkane linker reversibly inhibit the activity, of the copper amine oxidase from Arthrobacter globiformis (AGAO), with, K(i) values between 6 muM and 37 nM. In the crystal structure of a, Ru(II)-wire:AGAO conjugate, the wire occupies the AGAO active-site, substrate access channel, the trihydroxyphenylalanine quinone cofactor is, ordered in the "off-Cu" position with its reactive carbonyl oriented, toward the inhibitor, and the "gate" residue, Tyr-296, is in the "open", position. Head groups, tail-group substituents, and linker lengths all, influence wire-binding interactions with the enzyme.
