" Most people have probably met enzymes in school biology as the agents responsible for digesting our food, breaking down the starch of pasta, rice, potatoes into sugar and so on. Many meet them again as they face their washing machine, stained sports clothes in hand, and wonder whether or not to use a ‘biological’ detergent, containing added but unspecified ‘enzymes’ to do mysterious things to the clothes. As it happens, in both contexts the enzymes’ function is very similar, breaking down large chemical molecules into smaller bits that will wash away. People do not generally realize, however, that enzymes have much wider and more diverse roles and that, in effect, they orchestrate the whole of life. "
