2024 Chemistry Nobel Awarded for Cracking the Secret Code of Proteins
The Nobel Prize in Chemistry goes to Google DeepMind scientists Demis Hassabis and John Jumper, and biochemist David Baker, for cracking the code of protein constructions and creating totally new ones within the lab

The 2024 Nobel Prize in Chemistry was awarded on Wednesday to 3 scientists for locating how proteins—the constructing blocks of life and the dynamos that allow cells operate—do their jobs. Proteins construct muscle tissue and brains, assist hearts beat on time and filter out poisons, amongst many different important duties.
Half of the Nobel went collectively to researchers Demis Hassabis and John Jumper, each at Google DeepMind in London, for creating AlphaFold2—a man-made intelligence program that may predict a protein molecule’s form and construction from its chemical constructing blocks, referred to as amino acids. As a result of a protein’s form determines its operate, these predictions are extremely essential.
The opposite half of the prize went to structural biologist David Baker of the College of Washington for determining methods to design totally new proteins—molecules by no means seen in nature. A few of these synthetic proteins can function minuscule sensors whereas others could block the coronavirus that causes COVID. Baker will get 50 p.c of the prize cash, 11 million Swedish kronor, or about $1 million. Hassabis and Jumper will get the opposite 50 p.c.

As a result of proteins are such primary workhorses in biology, the flexibility to design synthetic ones is “absolutely mind-blowing,” mentioned Johan Åqvist, a member of the Nobel Committee for Chemistry, at a press convention following the announcement. Baker, woke up by a telephone name from Sweden, mentioned he was “very excited and very honored” to get the prize and that he “stood on the shoulders of giants.” Such researchers embody Christian Anfinsen, a U.S. scientist who acquired the 1972 chemistry Nobel after discovering that proteins’ form was nearly totally decided by their sequence of amino acids. (Baker additionally mentioned that when he instructed his spouse it was the Nobel Prize committee on the opposite finish of the road, she yelled so loudly with pleasure that he missed a number of the particulars about who had gained what.)
Among the many synthetic proteins that Baker is most enthusiastic about, he says, are molecules that block the way in which the COVID-causing coronavirus, SARS-CoV-2, infects human cells. He and his crew have been in a position to engineer these proteins at such a small measurement that they might be delivered in a nasal spray fairly than with the normal shot within the arm, he instructed Scientific American in a 2021 article. Making these “mini binders,” as he and his crew name them, would have been not possible earlier than he and different scientists deduced a number of the elementary guidelines that pull sure amino acids collectively and push others aside, figuring out the form of a protein and thus the way it interacts with different molecules, similar to elements of a virus.
In 2020, as Baker stood alongside a stage at a scientific assembly, ready to talk on a panel about protein design that I used to be moderating, he instructed me that he a lot prefers working within the lab on new molecules fairly than giving public speeches. With all the benefits of Nobel recognition, nevertheless, come calls for on a winner’s time. And Baker’s time within the lab will in all probability be restricted throughout the subsequent a number of months, at the least till after the December awards ceremony in Stockholm.
