The first protein to be recognized as catalyzing the phosphorylation of another protein using ATP was observed in 1954 by Eugene P. Kennedy at which time he described a liver enzyme that catalyzed the phosphorylation of casein. In 1956, Edmond H. Fischer and Edwin G. Krebs discovered that the interconversion between phosphorylase a and phosphorylase b was mediated by phosophorylation and dephosphorylation. The kinase that transferred a phosphoryl group to … WebMar 16, 2004 · Protein kinases are enzymes that covalently modify proteins by attaching phosphate groups (from ATP) to serine, threonine, and/or tyrosine residues. In so doing, the functional properties of the protein kinase’s substrates are modified. Protein kinases transduce signals from the cell membrane into the interior of the cell.

WebThere are two main types of protein kinase. The great majority are serine/threonine kinases, which phosphorylate the hydroxyl groups of serines and threonines in their targets and most of the others are tyrosine kinases, although additional types exist.
