James Batcheller Sumner (November 19, 1887 – August 12, 1955) was an American biochemist. He discovered that enzymes can be crystallized, for which he shared the Nobel Prize in Chemistry in 1946 with John Howard Northrop and Wendell Meredith Stanley. [3] . He was also the first to prove that enzymes are proteins . Biography.
10 de abr. de 2024 · James Batcheller Sumner was an American biochemist and corecipient, with John Howard Northrop and Wendell Meredith Stanley, of the 1946 Nobel Prize for Chemistry. Sumner was the first to crystallize an enzyme, an achievement that revealed the protein nature of enzymes.
The Nobel Prize in Chemistry 1946 was divided, one half awarded to James Batcheller Sumner "for his discovery that enzymes can be crystallized", the other half jointly to John Howard Northrop and Wendell Meredith Stanley "for their preparation of enzymes and virus proteins in a pure form" To cite this section.
Sumner’s findings were initially dismissed. However, building on this pioneering work, John Northrop developed the crystallization of pure enzymes and other proteins into an art form; and with it helped convince researchers that enzymes can be purified and isolated in tangible quantities.
The opponents gradually admitted Sumner's and Northrop's claims and the crowning recognition came in 1946 when the Nobel Prize was awarded to Sumner and Northrop. In 1948, Sumner was elected to the National Academy of Sciences (USA). The information on this page is based on content at Nobelprize.org © The Nobel Foundation.
Only in 1946, with the award of the Nobel Prize, was Sumner's work fully accepted. He received the award “for his discovery that enzymes can be crystallized.” The other half of the award went to J. H. Northrup and Wendell Stanley “for their preparation of enzymes and virus proteins in pure form.”
