2.7.1.19 malfunction CP12 is a small, redox-sensitive protein. Arabidopsis CP12 mutants have reduced levels of phosphoribulokinase and impaired function of the Calvin-Benson cycle 761618 2.7.1.19 malfunction deletion of phosphoribulokinase results in proportional increases to both the H2 yield and the specific production rate 761288 2.7.1.19 metabolism Calvin cycle 705819 2.7.1.19 metabolism Calvin cycle enzyme -, 704897, 705821 2.7.1.19 metabolism heterologous expression of phosphoribulokinase (PrkA) or Rubisco perturbs the physiology of Escherichia coli by changing its internal energy balance and carbon flow, which are not favored for in situ CO2 recycling by the Rubisco-based engineered pathway. Both PrkA and Rubisco enhances the glycolysis through the Embden-Meyerhof-Parnas pathway 761860 2.7.1.19 metabolism in the absence of Rubisco, phosphoribulokinase negatively affects growth, and in turn, the H2 production rate 761288 2.7.1.19 metabolism phosphoribulokinase (PRK) is an essential enzyme of the Calvin-Benson-Bassham cycle in photosynthesis. The oxyphototrophic phosphoribulokinase (PRK) is redox-regulated and can be further regulated by reversible association with both glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and oxidized chloroplast protein CP12. The resulting GAPDH/CP12/PRK complex is central in the regulation of the Calvin-Benson-Bassham cycle -, 762126 2.7.1.19 metabolism the Calvin cycle enzyme phosphoribulokinase is essential for growth on methanol -, 760933 2.7.1.19 physiological function phosphoribulokinase (PRK) is an essential enzyme of the Calvin-Benson-Bassham cycle in photosynthesis 762281 2.7.1.19 physiological function the enzyme strengthens the interaction between glyceraldehyde-3-phosphate dehydrogenase and chloroplast protein 12 within the supra-molecular complex 723160
