Edwin Gerhard Krebs was an American biochemist who shared (with Edmond H. Fischer) the 1992 Nobel Prize for Physiology or Medicine. They discovered reversible protein phosphorylation, a biochemical process that regulates the activities of proteins in cells and thus governs countless processes that are necessary for life. Malfunctions in protein phosphorylation have been implicated in the causation of diseases such as diabetes, cancer, and Alzheimer's disease.
