WebPhosphatases of the haloacid dehalogenase (HAD) superfamily of hydrolases are an ancient and very large class of enzymes that have evolved to dephosphorylate a wide range of low- and high molecular weight substrates with often exquisite specificities. HAD phosphatases constitute approximately one-fi … WebEsterases include lipases, which break ester bonds (between a carboxylic acid and an alcohol) in lipids, and phosphatases, which act analogously upon phosphates; a narrower category comprises the nucleases, which are phosphatases that hydrolyze nucleic acids. Glycosidases sever bonds between sugar molecules in carbohydrates.
WebA Classification of Protein Phosphatases. Protein phosphatases are the enzymes that hydrolyze phospho-ester bonds in phosphorylated proteins. They play critical roles in cell regulation, given their ability to reverse the effects of protein kinases.
