3-PHOSPHO-D-GLYCERATE CARBOXYLYASE[DIMERIZING]

3-PHOSPHO-D-GLYCERATE CARBOXYLYASE[DIMERIZING] Chemische Eigenschaften,Einsatz,Produktion Methoden

• Verwenden

  D-Ribulose 1,5-Diphosphate Carboxylase from spinach has been used:
  
  • as a test protein in pepsin digestion studies
  • as an innocuous or non-hazardous protein sample to test its effect on human intestinal epithelial cell lines
  • in isothermal titration calorimetry (ITC), and radiolabeled binding assays with abscisic acid
  
  

• Allgemeine Beschreibung

  Exists as a 557?kDa hexadecamer composed of eight heavy chains each with a molecular weight of approximately 56?kDa and eight light chains of molecular weight 14?kDa. Each molecule contains one magnesium ion.
  pH optimum: ~7.9.
  K_M for CO₂: ~0.45 mM.
  Ribulose diphosphate becomes inhibitory at concentrations exceeding 0.7 mM. Orthophosphate and ammonium sulfate are competitive inhibitors. 3-Phosphoglycerate is a noncompetitive inhibitor.

• Biochem/physiol Actions

  D-Ribulose 1,5-Diphosphate Carboxylase (RUBISCO) depends on Rubisco activase and chaperones for activation. It participates in plant photorespiration events by catalyzing the carboxylation and oxygenation of ribulose-1,5-bisphosphate. Abscisic acid inhibits the carboxylation activity of Rubisco.
