<p><b>New page</b></p><div>The biochemical identity of enzymes was still unknown in the early 1900s. Many scientists observed that enzymatic activity was associated with proteins, but others (such as Nobel laureate [[Richard Willstätter]]) argued that proteins were merely carriers for the true enzymes and that proteins ''per se'' were incapable of catalysis. In 1926, [[James B. Sumner]] showed that the enzyme [[urease]] was a pure protein and crystallized it; he did likewise for the enzyme [[catalase]] in 1937. The conclusion that pure proteins can be enzymes was definitively demonstrated by [[John Howard Northrop]] and [[Wendell Meredith Stanley]], who worked on the digestive enzymes [[pepsin]] (1930), [[trypsin]] and [[chymotrypsin]]. These three scientists were awarded the 1946 Nobel Prize in Chemistry.</div>FuzzyBot
