Opis ogólny
D-Ribulose 1,5-Diphosphate Carboxylase (RUBISCO) amounts to 50% of the total spinach leaves associated soluble protein.
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.
KM 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.

Zastosowanie
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
Działania biochem./fizjol.
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.
Definicja jednostki
One unit will convert 1.0 μmole of D-RuDP and CO2 to 2.0 μmoles of D-3-phosphoglycerate per min at pH 7.8 at 25°C.

Rubisco gene expression was examined in detail in rice (Oryza sativa L.) leaves at different positions, i.e. expanding, mature, and senescent leaves. Rubisco small subunit (RBCS) synthesis and RBCS mRNA levels were maximal in expanding leaves and gradually became lower

A well-known case of evolutionary adaptation is that of ribulose-1,5-bisphosphate carboxylase (RubisCO), the enzyme responsible for fixation of CO2 during photosynthesis. Although the majority of plants use the ancestral C3 photosynthetic pathway, many flowering plants have evolved a derived pathway

Oxidative stress and inflammation contribute significantly to atherogenesis. We and others have demonstrated that mildly elevated serum bilirubin levels protect against coronary and peripheral atherosclerosis, most likely due to the antioxidant and anti-inflammatory activities of bilirubin.

Chloroplasts are the primary energy suppliers for plants, and much of the total leaf nitrogen is distributed to these organelles. During growth and reproduction, chloroplasts in turn represent a major source of nitrogen to be recovered from senescing leaves and

Characterized by a photocatalysis property, nanoanatase is closely related to the photosynthesis of spinach. It could not only improve light absorbance, transformation from light energy to electron energy, and active chemical energy, but also promote carbon dioxide (CO(2)) assimilation of
