Three scientists have been honoured in this year鈥檚 Nobel Prize in Chemistry for 鈥渢aking control of evolution鈥 through their discoveries of new enzymes.

One-half of the SKr9聽million (拢770,000) prize goes to Frances Arnold, professor of chemical engineering, bioengineering and biochemistry at the California Institute of Technology; the other half is shared between George Smith, formerly professor at the University of Missouri, and Sir Gregory Winter, from the MRC Laboratory of Molecular Biology at the University of Cambridge.

Professor Arnold becomes the fifth woman to win the Nobel for chemistry during its 117-history and is recognised 鈥渇or the directed evolution of enzymes鈥 鈥 which she succeeded in doing for the first time in 1993.

The process, which has since been refined, can be used in environmentally friendly manufacturing of chemical substances as well as renewable fuels.

Sir Gregory鈥檚 win marks the 12th Nobel for the Cambridge laboratory, and is given in recognition of his work with Professor Smith developing a new method of directed evolution known as 鈥減hage display鈥. The process uses viruses that infect bacteria to evolve new proteins.

Phage display is now used in the production of new pharmaceuticals and has produced antibodies that can neutralise toxins, counteract autoimmune diseases and even cure metastatic cancer.

A genetic engineer, Sir Gregory is also the current master of Trinity College, Cambridge and becomes the 107th Nobel laureate from the university.

Announcing the prize in Stockholm on 3聽October, the Nobel committee said that the discovery of directed evolution 鈥渨ill bring the greatest benefit to humankind鈥.

Dame Carol Robinson, president of the Royal Society of Chemistry in the UK, congratulated all three laureates and said that the directed evolution of enzymes and antibody technology 鈥渁re now transforming medicine鈥.

鈥淭oday鈥檚 Nobel Prize in Chemistry highlights the tremendous role of chemistry in contributing to many areas of our lives including pharmaceuticals, detergents, green catalysis and biofuels. It is a great advert for chemistry to have impact in so many areas,鈥 she added.
