LuxS-independent formation of AI-2 from ribulose-5-phosphate
BMC Microbiology, 2008 Background In many bacteria, the signal molecule AI-2 is generated from its precursor S-ribosyl-L-homocysteine in a reaction catalysed by the enzyme LuxS.

Inhibition of ribulose bisphosphate carboxylase by substrate ribulose 1,5-bisphosphate.
Journal of Biological Chemistry, 1983 Substrate ribulose bisphosphate is a potent and a weak inhibitor of the rate of CO2/Mg2+ activation in the carboxylase purified from spinach leaves and Rhodospirillum rubrum, respectively. At 2 degrees C, the concentration of ribulose bisphosphate required for 50% inhibition of the initial rate of CO2/Mg2+ activation was less than 0.4 microM for the ...

Inhibition of ribulose-1,5-bisphosphate carboxylase/oxygenase by ribulose-1,5-bisphosphate epimerization and degradation products [PDF]
Biochemical and Biophysical Research Communications, 1978 Abstract Xylulose-1,5-bisphosphate in preparations of ribulose-1,5-bisphosphate (ribulose-P2) arises from non-enzymic epimerization and inhibits the enzyme. Another inhibitor, a diketo degradation product from ribulose-P2, is also present. Both compounds simulate the substrate inhibition of ribulose-P2 carboxylase/oxygenase previously reported for ...

Identification of Interactions between Abscisic Acid and Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase. [PDF]
PLoS ONE, 2015 Abscisic acid ((+)-ABA) is a phytohormone involved in the modulation of developmental processes and stress responses in plants. A chemical proteomics approach using an ABA mimetic probe was combined with in vitro assays, isothermal titration calorimetry (

Exploring the oxygenase function of Form II Rubisco for production of glycolate from CO2
AMB Express, 2021 The oxygenase activity of Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) converts ribulose-1,5-bisphosphate (RuBP) into 2-phosphoglycolate, which in turn channels into photorespiration, resulting in carbon and energy loss in higher plants.

Grafting Tobacco onto Nutrient-efficient Rootstocks Improves Photosynthesis
Journal of the American Society for Horticultural Science, 2021 Potassium deficiency is a major problem limiting tobacco (Nicotiana tabacum) growth, and grafting has the potential to alleviate it. To compare the photosynthetic performance of grafted tobacco under different potassium levels, tobacco Yunyan 87 (main ...

Continuous artificial synthesis of glucose precursor using enzyme-immobilized microfluidic reactors
Nature Communications, 2019 Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) is a difficult enzyme to work with. Here, the authors covalently immobilized it in a microfluidic reactor to enhance its storage/thermal stabilities and reusability, which enabled the continuous ...
