Nature of the active sites in haemocyanin and iron nickel hydrogenases: the bond valence sum approach
Abstract
The available crystal structure data on deoxyhaemocyanin and the extended X-ray absorption fine structure data on oxygenated haemocyanin and various forms of iron nickel hydrogenases have been analysed by the bond valence sum method to examine the nature of the co-ordination spheres around the metals in these enzymes.
