- 1997 Nobel Prize in Chemistry
Sir John Ernest Walker (born 7 January 1941), British chemist who was co-recipient, with Paul D. Boyer, of the Nobel Prize for Chemistry in 1997 for their explanation of the enzymatic process that creates adenosine triphosphate (ATP). Walker and Boyer’s findings offer insight into the way life-forms produce energy.

Major Academic Achievements
Focusing on the chemical and structural composition of ATP synthase, John Walker determined the sequence of amino acids that make up the synthase’s protein units. By 1994, working with X-ray crystallographers, Walker clarified the three-dimensional structure of the ATP synthase. Since this structure, Walker and his colleagues have produced most of the crystal structures in the PDB of mitochondrial ATP synthase, including transition state structures and protein with bound inhibitors and antibiotics. Scientists trained in Walker's group at the MRC Laboratory of Molecular Biology in Cambridge or MRC Mitochondrial Biology Unit have gone on to determine crystal bacterial complex I and cryo-EM maps of mitochondrial complex I and vacuolar type ATPases.
