AGAO IN COMPLEX WITH RUTHENIUM-C4-WIRE AT 1.73 ANGSTROMS
Overview
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.
About this Structure
2BT3 is a Single protein structure of sequence from Arthrobacter globiformis with CU, NA, SO4, R4A and GOL as ligands. Active as Amine oxidase (copper-containing), with EC number 1.4.3.6 Known structural/functional Site: AC1. Full crystallographic information is available from OCA.
