This is Scientific American's 60 second science. I'm Steve Mirsky. At the Lindau Nobel Laureate Meeting at Lindau Germany. This will just take a little bit more time than our usual may?. Edmond Fischer won the Nobel Prize in Physiology 1 of Medicine in 1992 for his discoveries with Edwin Krebs about the way proteins get activated 2 and cellular 3 processes get regulated via a simple process called phosphorylation. Now 91 years old, Fisher spoke 4 to students at the Lindau Nobel Laureate Meeting about the difference between research when he was working in the 1950s and the way it's conducted today.
Science was conducted in a totally different way. In those days, in fact since the days of Claude Bernard, the Frech physiologist 5 who first showed the glycogenic action of the pancreas, when observed a physiological 6 phenomenon, and then one try to detect the factors, enzymes 8, hormones 9 responsible for it whereas today, by and large, you see other way around. First enzyme 7 proteins are discovered, then with the completion of I don't know how many geno sequencing projects, hundreds are being discovered. And then by overexpressing them, knocking them in and out, one tries to determine their function. So to paraphrase 10 B D, we went from 6 functions in search of an enzyme, to hundreds of enzymes and protein in search of a function.
Thanks for the minutes, for Scientific American's sixty second science from the Lindau Nobel Laureate meeting. I'm Steve Mirsky.
