Phosphatase enzyme action
A protein phosphatase is an enzyme that dephosphorylates an amino acid residue of its protein substrate. Whereas protein kinases act as signaling molecules by phosphorylating proteins, phosphatases remove the phosphate group, which is essential if the system of intracellular signaling is to be able to … See more In biochemistry, a phosphatase is an enzyme that uses water to cleave a phosphoric acid monoester into a phosphate ion and an alcohol. Because a phosphatase enzyme catalyzes the hydrolysis of … See more In contrast to kinases, phosphatase enzymes recognize and catalyze a wider array of substrates and reactions. For example, in humans, … See more • Acid phosphatase • Alkaline phosphatase • Endonuclease/Exonuclease/phosphatase family See more Phosphatases catalyze the hydrolysis of a phosphomonoester, removing a phosphate moiety from the substrate. Water is split in the reaction, with … See more Within the larger class of phosphatase, the Enzyme Commission recognizes 104 distinct enzyme families. Phosphatases are classified by … See more • Phosphatases at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more WebPhosphatase is an enzyme that removes a phosphate group from its substrate by hydrolysing phosphoric acid monoesters into a phosphate ion and a molecule with a free hydroxyl group. This action is directly opposite to that of phosphorylases and kinases, which attach phosphate groups to their substrates by using energetic molecules like ATP. ...

WebThe activity of the enzyme alkaline phosphatase can be conveniently measured spectrophotometrically using 4-nitrophenylphos- phate as substrate. This article describes an integrated series of experiments involving the enzyme in which a number of valuable experimental and analytical skills can be developed. Phosphatases act in opposition to kinases/phosphorylases, which add phosphate groups to proteins. The addition of a phosphate group may activate or de-activate an enzyme (e.g., kinase signalling pathways ) or enable a protein-protein interaction to occur (e.g., SH2 domains ); therefore phosphatases are integral to many signal transduction pathways. Phosphate addition and removal do not necessarily correspond to enzyme activation or inhibition, and that several e…
