John E. Walker (born 7 January 1941) is a British biochemist who was awarded the Nobel Prize in Chemistry in 1997 for his work on the enzymatic mechanism underlying the synthesis of adenosine triphosphate (ATP). He shared the prize with Paul D. Boyer and Jens C. Skou.

Early Life and Education

John Ernest Walker was born in Halifax, West Yorkshire, England. He attended Rastrick Grammar School and later studied chemistry at St Catherine's College, Oxford, where he received his BA degree in 1964. He completed his PhD at the University of Oxford in 1969 under the supervision of Edward Abraham.

Career and Research

After completing his PhD, Walker conducted postdoctoral research at the University of Wisconsin–Madison and the French National Centre for Scientific Research (CNRS) in France. In 1974, he joined the Medical Research Council's Laboratory of Molecular Biology in Cambridge, where he began his pioneering work on ATP synthesis.

Walker is best known for his elucidation of the structure and function of ATP synthase, an enzyme that plays a crucial role in the production of ATP, the energy currency of the cell. His research provided significant insights into the mechanism by which ATP is synthesized in the mitochondria.

Nobel Prize

In 1997, Walker was awarded the Nobel Prize in Chemistry along with Paul D. Boyer for their elucidation of the enzymatic mechanism underlying the synthesis of ATP. Jens C. Skou was also awarded a share of the prize for his discovery of the sodium-potassium pump.

Personal Life

John E. Walker is married and has two children. He continues to be active in the scientific community and has received numerous awards and honors for his contributions to biochemistry.
