The four main classes of protein phosphatases (PP-1, 2A, 2B and 2C), although differing in their ability to dephosphorylate phosphopeptide substrates, invariably display a marked preference toward phosphothreonyl peptides over their phosphoseryl counterparts. Conversely, all the acidic and alkaline phosphatases
