WebJun 22, 2024 · Steps in the signal transduction pathway often involve the addition or removal of phosphate groups which results in the activation of proteins. Enzymes that transfer phosphate groups from ATP to a protein are called protein kinases. Many of the relay molecules in a signal transduction pathway are protein kinases and often act on … Web33.5.3 Acid Phosphatase. Phosphatases or phosphomonoesterases are the hydrolytic enzymes that cleave the ester bond between the phosphate group and the organic residue of the organic phosphates. Based on the optimum pH for the activity, phosphatases are of two kinds: acid and alkaline.
WebDephosphorylation. In biochemistry, dephosphorylation is the removal of a phosphate (PO 43−) group from an organic compound by hydrolysis. It is a reversible post-translational … WebDephosphorylation is the removal of a phosphate (PO 4 3−) group by hydrolysis. To dephosphorylate a protein or DNA, an enzyme or hydrolase that cleaves ester bonds is required. For example, phosphatases remove phosphate groups by hydrolyzing phosphoric acid monoesters into a phosphate ion and a molecule with a free hydroxyl …
