Detailed explanation-1: -Phosphatase 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.

Detailed explanation-2: -For example, phosphatases remove phosphate groups by hydrolyzing phosphoric acid monoesters into a phosphate ion and a molecule with a free hydroxyl (−OH) group.

Detailed explanation-3: -Protein phosphorylation is regulated by protein kinases, each of which covalently attaches a phosphate group to an amino acid side chain on serine (Ser), threonine (Thr), or tyrosine (Tyr), and by protein phosphatases, each of which, conversely, removes a phosphate group from a phosphoprotein (Figure 1).

Detailed explanation-4: -Phosphatase: This kind of enzyme removes phosphate groups from molecules. Phosphatases hydrolyze phosphoric acid monoesters into phosphate ions and a free hydroxyl group molecule.

Detailed explanation-5: -Phosphatases are the extracellular enzymes that catalyze the hydrolysis of phospho-ester bonds in organic P-containing substrates releasing inorganic P in the form of orthophosphates that can be used by soil biota and plants.
