One-gene-one-enzyme hypothesis

WebThe one gene-one enzyme hypothesis was first proposed by the English physician Archibald Garrod in 1909. It suggests that each gene codes for a single, specific enzyme. In other words, under this hypothesis, each gene would be responsible for the enzyme facilitating a single step in a metabolic process. http://centennial.rucares.org/index.php?page=One-gene_One-enzyme

The one gene–one enzyme hypothesis is the idea that genes act through the production of enzymes, with each gene responsible for producing a single enzyme that in turn affects a single step in a metabolic pathway. The concept was proposed by George Beadle and Edward Tatum in an influential 1941 paper on genetic mutations in the mold Neurospora crassa, and subsequently was dubbed the "one gene–one enzyme hypothesis" by their collaborator Norman Horowitz.
