August undefined, 2024

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… WebApr 19, 2024 · Phosphatase is an enzyme that is responsible for removing a phosphate group from a biomolecule. Thus phosphatase functions in opposition to the action of a kinase. The known sources of the phosphate group of transfer are the high-energy compounds ATP or GTP.
