Phosphatases are a group of hydrolases that catalyze the hydrolysis of a phosphomonoester, removing a phosphate moiety from the substrate. In contrast to kinases, which phosphorylate substrate, phosphatases dephosphorylate the substrate. Phosphorylation is a fundamental and pervasive mechanism widely known to regulate the functions of proteins. Phosphatases and kinases act as regulators of protein reversible phosphorylation in the cell, which constitutes a major form of signaling and an essential mechanism of regulation in all living organisms. Protein phosphatases are the enzymes that hydrolyze phospho-ester bonds in phosphorylated proteins. Eukaryotic protein phosphatases are structurally and functionally diverse enzymes that are represented by three distinct gene families, including the PPPs (phosphoprotein phosphatases), PPMs (metal-dependent protein phosphatases) and PTPs (protein tyrosine phosphatases). PPPs and PPMs dephosphorylate phosphoserine and phosphothreonine residues, whereas the PTPs dephosphorylate phosphotyrosine amino acids.
