ABSTRACT
In Chapter 2 we saw that hydrogenases of the three basic types are made by organisms that have existed over billions of years. In Chapter 6, the structures of the proteins were laid out in three dimensions. In Chapter 7 we saw that the metal centres of the protein could exist in particular chemical states. We can now begin to understand how the hydrogenases catalyse their reactions with such extraordinary efficiency. Furthermore we ask, can similar catalysts be constructed artificially?
