D-リブロース1,5-二リン酸カルボキシラーゼ FROM SPINACH 化学特性,用途語,生産方法
使用
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
一般的な説明
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.

M for CO
2: ~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.
