Disrupting ribulose-5-phosphate metabolic flux enhances riboflavin production in Escherichia coli BL21(DE3). [PDF]

PLoS ONE
Riboflavin (vitamin B2) is an essential water-soluble vitamin. To increase its production in a previously engineered strain, R203, we employed metabolic engineering strategies to improve the supply of ribulose-5-phosphate, a key precursor.

Crystal structure of a novel homodimeric l‐ribulose 3‐epimerase from Methylomonus sp.

FEBS Open Bio, 2021
d‐Allulose has potential as a low‐calorie sweetener which can suppress fat accumulation. Several enzymes capable of d‐allulose production have been isolated, including d‐tagatose 3‐epimerases.

Ribulose-1,5-bisphosphate regeneration in the Calvin-Benson-Bassham cycle: Focus on the last three enzymatic steps that allow the formation of Rubisco substrate

Frontiers in Plant Science, 2023
The Calvin-Benson-Bassham (CBB) cycle comprises the metabolic phase of photosynthesis and is responsible for carbon fixation and the production of sugar phosphates.

Experimental evidence for extra proton exchange in ribulose 1,5-bisphosphate carboxylase/oxygenase catalysis

Communicative & Integrative Biology, 2022
Despite considerable advances in the past 50 y, the mechanism of ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco) catalysis is still not well understood.

Ribulose Diphosphate Carboxylase in Thiorhodaceae [PDF]

Journal of General Microbiology, 1963
SUMMARY: The concentration of ribulose 1,5-diphosphate (RuDP) carboxylase, the enzyme which catalyses the conversion of ribulose 1,5-diphosphate + CO2 to 3-phosphoglyceric acid, was partially repressed in some Thiorhodaceae organisms when these were grown on certain organic compounds.

Exogenous trehalose differently improves photosynthetic carbon assimilation capacities in maize and wheat under heat stress

Journal of Plant Interactions, 2022
High temperature inhibits the growth and development of maize (Zea mays L.) and wheat (Triticum aestivum L.) seedlings. The current study attempts to elucidate the underlying mechanisms of exogenous trehalose for the improvement of maize and wheat ...

Improving the Production of Riboflavin by Introducing a Mutant Ribulose 5-Phosphate 3-Epimerase Gene in Bacillus subtilis

Frontiers in Bioengineering and Biotechnology, 2021
Ribulose 5-phosphate (Ru5P) and guanosine 5′-triphosphate (GTP) are two key precursors of riboflavin, whereby Ru5P is also a precursor of GTP. Ribulose 5-phosphate 3-epimerase (Rpe) catalyzes the conversion of ribulose 5-phosphate into xylulose 5 ...

Generation of an Escherichia coli strain growing on methanol via the ribulose monophosphate cycle

Nature Communications, 2022
Using one carbon compounds as feedstock is a promising approach in abating climate change. Here, the authors report the conversion of E. coli into a synthetic methylotroph that assimilates methanol via the ribulose monophosphate cycle and a set of ...
