The 2024Nobel Prizein chemistry has been awarded to three scientist who sour in two intimately loop fields of protein science .
David Baker , a professor of biochemistry at the University of Washington , receive half of the 11 million Swedish krona ( $ 1.06 million ) swag for his piece of work on computational protein design — a tool that enables researcher to design and create completely novel protein structures with properties unlike any found in nature .
A panel announces the winners of the 2024 Nobel Prize in Chemistry on October 9th.
The second half of the prize was shared betweenDemis HassabisandJohn Jumper , respectively the CEO and director of Google DeepMind , for their work on protein structure prediction . TheAI - power program AlphaFold2 , release in 2021 , can foreshadow the three - dimensional structure of any protein from the amino group acid sequence encoded in DNA , revolutionize our understanding of how protein and molecules in living systems interact with each other .
" Proteins are the molecules which enable life,“Heiner Linke , chairwoman of the Nobel Committee for Chemistry , said during the proclamation ceremonial in Sweden this morning ( Oct. 9 ) .
A protein has ten of K of individual atoms , and its specific function is determined by the exact positions of these atoms , with links and fold between the dissimilar part of the corpuscle creating a unique 3D shape . " To understand how life works , we first ask to realize the shape of proteins , " Linke allege .
Protein molecules are mould from many case-by-case units called amino battery-acid , which are encode by three " letter " DNA succession . It should therefore be potential to predict the 3D structure of a particular protein from this chronological sequence of amino dose . But this job has been thwarting scientists for tenner because there are many potential slipway for proteins to close up .
In 2020 , Hassabis and Jumper finally cracked this computer code by develop a political program telephone AlphaFold2 , which boosted the accuracy of structure predictions from 40 % to 90 % . The AI program was train on a database of protein sequences and protein structures and looks for correlation between the positions of amino acids across thousands of examples . The organisation then iteratively refine these resolution down to a individual predicted 3D body structure .
In the years since it was released , this instrument has dramatically improved our understanding of thousands of protein - mediated processes , including antibiotic resistor , and it is now possible to mine these database for protein with antecedently obscure procedure , such as plastic - degrading enzyme .

Protein pattern approaches this same job from the opposite direction , enable investigator to visualize the idealistic 3D protein structure for a particular procedure and play backward to calculate the amino acid sequence necessitate to synthesise it . In 2003 , Baker developed a computer program calledRosettathat combines shorter amino acid fragments from an existing database , successively tweaking and optimizing the sequence to gibe the expect 3D shape .
" David Baker open up a completely new world of protein structure , " Johan Åqvist , a member of the Nobel Committee for Chemistry , said during the annunciation . " It ’s only your mental imagery which sets the limit for what you may do here . " Rosetta has since help to plan hundreds of new proteins with diverse app , browse from inhibiting the COVID spike protein to dissemble as biologic detector for opioids in the environment .
Speaking to The Royal Swedish Academy of Sciences Secretary General Hans Ellegren be the trophy announcement , Baker said he felt " very excited and very honored " and had been " really deeply inspired by others in the line of business and people I ’ve worked with . "
