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.
