(1999) Gunter Blobel
GĂźnter Blobel (born May 21, 1936) is a German American biologist. Blobel was awarded the 1999 Nobel Prize in Physiology or Medicine for the discovery of signal peptides. Signal peptides form an integral part of protein targeting, a mechanism for cells to direct newly synthesized protein molecules to their proper location by means of an \"address tag\" (i.e. a signal peptide) within the molecule.
