Leírás

Általános leírás

Recombinant λ PPase expressed in E. coli. A 221-amino acid, Mn²⁺-dependent, protein phosphatase. Hydrolyzes phosphate groups on serine, threonine, tyrosine, or histidine residues. Inhibited by orthovanadate. Note: 1KU = 1,000 units.

Research Area: Cell Signaling
The protein phosphatase encoded by bacteriophage λ (λPP) is part of a family of Ser/Thr phosphatases (Ser/Thr PPases), which includes eukaryotic protein phosphatases 1 (PP1), 2A (PP2A), and 2B (calcineurin).

Alkalmazás

Protein Phosphatase, Lambda, Recombinant, E. coli is suitable for the detection of phospho-KRAS.

Biokémiai/fiziológiai hatások

Protein phosphatases play a crucial role in embryonic development, metabolic homeostasis, stress responses, cell cycle transitions, and numerous other vital biological processes.

Figyelmeztetés

Toxicity: Standard Handling (A)

Egység definíció

One unit is defined as the amount of enzyme that will hydrolyze 1.0 nmol of pNPP per min at 30°C, pH 7.8. 20-200 Units will typically remove >95% of phosphates from serine/threonine residues in 0.1 nmol of protein in 30 min. 100-1000 Units will typically remove >95% of phosphates from tyrosine in 0.1 nmol of protein in 30 min.
