WebPhosphatases have the opposite function of kinases. They remove the phosphate group from phosphoproteins by hydrolyzing phosphoric acid monoesters into a phosphate group and a molecule with a free hydroxyl group ( 28, 29 ). Enzymatic removal reverts the protein to a non-phosphorylated state with a kinetics more rapid than kinases ( 30 ). WebA protein phosphatase is a phosphatase enzyme that removes a phosphate group from the phosphorylated amino acid residue of its substrate protein. Protein phosphorylation is one of the most common forms of reversible protein posttranslational modification ( PTM ), with up to 30% of all proteins being phosphorylated at any given time. iot gateway companiesWebAlkaline phosphatase (ALP) represents a group of enzymes that remove phosphate groups from molecules such as nucleotides and proteins, and they work most effectively in an alkaline environment of pH 9–10 (Evans, 2009 ). onu xpon wifi ac1200
