Phosphatase dephosphorylation
WebDephosphorylation is probably catalyzed by a metal-activated water molecule that acts as nucleophile in a mechanism similar to that proposed for the PPP family. A recent kinetic analysis of PP2Cα by Denu and colleagues [24] indicated that Mn 2+ and Fe 2+ are the most effective divalent metal ions in promoting dephosphorylation reactions ...
