3D STRUCTURE OF COTA INCUBATED WITH CUCL2
Overview
The multi-copper oxidases oxidise substrate molecules by accepting, electrons at a mononuclear copper centre and transferring them to a, trinuclear centre. Dioxygen binds to the trinuclear centre and, following, the transfer of four electrons, is reduced to two molecules of water. The, precise mechanism of this reduction has been unclear, but recent X-ray, structural studies using the CotA endospore coat protein from Bacillus, subtilis have given further insights into the principal stages. It is, proposed that the mechanism involves binding of the dioxygen into the, trinuclear centre so that it is sited approximately symmetrically between, the two type 3 copper ions with one oxygen atom close to the type 2 copper, ion. Further stages involve the formation of a peroxide intermediate and, ... [(full description)]
