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… WebDec 30, 2024 · The enzyme is an important modulator regulating the intracellular fructose-2,6-bisphosphate level.
