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.

Low temperature impact on photosynthetic parameters of coffee genotypes Impacto de baixas temperaturas em parâmetros fotossintéticos de genótipos de cafeeiro

Pesquisa Agropecuária Brasileira, 2009
The objective of this work was to evaluate photoprotective mechanisms related to low positive temperatures in Coffea canephora (Conilon clones 02 and 153) and C. arabica ('Catucaí' IPR 102) genotypes, involved in cold temperature tolerance. To accomplish

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 ...

The methionine salvage pathway in Bacillus subtilis [PDF]

, 2002
BACKGROUND: Polyamine synthesis produces methylthioadenosine, which has to be disposed of. The cell recycles it into methionine through methylthioribose (MTR). Very little was known about MTR recycling for methionine salvage in Bacillus subtilis. RESULTS:

Rubisco evolution in C4 eudicots: an analysis of Amaranthaceae sensu lato [PDF]

, 2015
BACKGROUND Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase) catalyses the key reaction in the photosynthetic assimilation of CO₂. In C₄ plants CO₂ is supplied to Rubisco by an auxiliary CO₂-concentrating pathway that helps to maximize the ...

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 ...

Metabolic flexibilities and vulnerabilities in the pentose phosphate pathway of the zoonotic pathogen Toxoplasma gondii.

PLoS Pathogens, 2022
Metabolic pathways underpin the growth and virulence of intracellular parasites and are therefore promising antiparasitic targets. The pentose phosphate pathway (PPP) is vital in most organisms, providing a reduced form of nicotinamide adenine ...

Interactions Between Carbon Metabolism and Photosynthetic Electron Transport in a Chlamydomonas reinhardtii Mutant Without CO2 Fixation by RuBisCO

Frontiers in Plant Science, 2022
A Chlamydomonas reinhardtii RuBisCO-less mutant, ΔrbcL, was used to study carbohydrate metabolism without fixation of atmospheric carbon. The regulatory mechanism(s) that control linear electron flow, known as “photosynthetic control,” are amplified in ...

Regulation of Soybean Net Photosynthetic CO(2) Fixation by the Interaction of CO(2), O(2), and Ribulose 1,5-Diphosphate Carboxylase.

Plant Physiology, 1974
Kinetic properties of soybean net photosynthetic CO(2) fixation and of the carboxylase and oxygenase activities of purified soybean (Glycine max [L.] Merr.) ribulose 1, 5-diphosphate carboxylase (EC 4.1.1.39) were examined as functions of temperature, CO(

Assay of the Carboxylase Activity of Rubisco from Chlamydomonas reinhardtii

Bio-Protocol, 2015
The performance of the carbon-fixing enzyme, ribulose 1, 5-bisphosphate carboxylase/oxygenase (EC 4.1.1.39, Rubisco), controls biomass accumulation in green plants, algae and most autotrophic bacteria.
