galactose oxidase is a copper-dependent enzyme that accomplishes 2e- substrate oxidation by pairing a single copper with an unusual cysteinylated tyrosine (Cys-Tyr) redox cofactor. The active site of GO contains only a single Cu . Post-translational biogenesis of Cys-Tyr is copper- and O2-dependent, resulting in a self-processing enzyme system. Cu(I) and Cu(II) enzyme states, Cu(I) active site modeling: on model uses the crystal structure of apo pre-processed GO (PDB ID 2VZ1) with Cu(I) manually added as the starting structure, while the other uses the crystal structure of processed Cu(II)-GO (PDB ID 1GOF) with the Cys-Tyr crosslink manually removed. In both cases, the model includes Cys228, Tyr272, Tyr495, His496 and His581 residues. Cu(I) activation mechanism, overview |
