Chemistry Nobel goes to three scientists who ‘harnessed the power of evolution’

STOCKHOLM (AP) — Three researchers who “harnessed the power of evolution” to produce enzymes and antibodies that have led to a new best-selling drug and biofuels won the Nobel Prize in chemistry on Wednesday.

Frances Arnold of the California Institute of Technology was awarded half of the 9-million-kronor ($1.01 million) prize, while the other half will be shared by George Smith of the University of Missouri and Gregory Winter of the MRC molecular biology lab in Cambridge, England.

The Royal Swedish Academy of Sciences, which chose the winners, said Arnold, 62, conducted the first directed evolution of enzymes, whose uses include “more environmentally friendly manufacturing of chemical substances such as pharmaceuticals and the production of renewable fuels.”

Smith, 77, developed a method to evolve new proteins and Winter used the method to evolve antibodies, which are disease-fighting proteins in the blood.

The first pharmaceutical based on Winter’s work was approved for use in 2002 and is employed to treat rheumatoid arthritis, psoriasis and inflammatory bowel diseases, the academy said. The chemical name of the drug is adalimumab, which has several trade named including Humira, one of the top-selling drugs in the world.

Smith, speaking to The Associated Press after learning about this Nobel win, credited others for the work that led to his breakthrough.

“Very few research breakthroughs are novel. Virtually all of them build on what went on before. It’s happenstance. That was certainly the case with my work,” he said Wednesday. “Mine was an idea in a line of research that built very naturally on the lines of research that went before.”

Smith said he learned of the prize in a pre-dawn phone call from Stockholm.

“It’s a standard joke that someone with a Swedish accent calls and says ‘You won!’ But there was so much static on the line, I knew it wasn’t any of my friends,” he said.

American Chemical Society president Peter Dorhout praised the Nobel winners, saying “the laureates have used chemistry to accelerate the evolution of natural biological molecules that act as the critical machinery for living organisms.

“The breakthroughs from these researchers enable that to occur thousands of times faster than nature to improve medicines, fuels and other products,” he said.

Experts said the developments for which the winners won the 2018 prize can be more ecological than many other chemical processes.
