Exploring the oxygenase function of Form II Rubisco for production of glycolate from CO2

open access: yesAMB 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.

Protocol to analyze the inhibitory effect of free organic carbon generated by chemoautotrophic bacteria on their CO2 fixation

open access: yesSTAR Protocols, 2023
Summary: Here, we present a protocol to analyze the inhibition of self-generated extracellular free organic carbon (EFOC) on CO2 fixation by chemoautotrophic bacteria. We detail the construction and operation of membrane reactor, followed by a simulation

Competition of Pyridoxal 5'-Phosphate with Ribulose 1,5-Bisphosphate and Effector Sugar Phosphates at the Reaction Centers of the Spinach Ribulose 1,5-Bisphosphate Carboxylase/Oxygenase [PDF]

open access: yes, 1980
The Stimulation of the carboxylase reaction by effectors of ribulose 1,5-bisphosphate carboxyl­ ase/oxygenase displays higher sensitivity towards pyridoxal 5'-phosphate inhibition than the catalytical process itself. Pyridoxal 5'-phosphate binding to the

Effect of salicylic acid pretreatment on cadmium toxicity in wheat

open access: yesBiologia Plantarum, 2010
Cadmium (100, 400 and 1000 μM CdCl2) treatments resulted in the inhibition of root dry biomass, root elongation and increased Cd accumulation in wheat (Triticum aestivum L.) roots.

Continuous artificial synthesis of glucose precursor using enzyme-immobilized microfluidic reactors

open access: yesNature 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 ...

Low Salinity Improves Photosynthetic Performance in Panicum antidotale Under Drought Stress

open access: yesFrontiers in Plant Science, 2020
Salinity and drought are two often simultaneously occurring abiotic stresses that limit the production of food crops worldwide. This study aimed to distinguish between the separate and combined impacts of drought and salinity on the plant response ...

Effects of OsRCA Overexpression on Rubisco Activation State and Photosynthesis in Maize

open access: yesPlants, 2023
Ribulose–1,5–bisphosphate carboxylase/oxygenase (Rubisco) is the rate–limiting enzyme for photosynthesis. Rubisco activase (RCA) can regulate the Rubisco activation state, influencing Rubisco activity and photosynthetic rate. We obtained transgenic maize

Photorespiration-Induced Reduction of Ribulose Bisphosphate Carboxylase Activation Level [PDF]

open access: yesPlant Physiology, 1985
Leaf photosynthesis and ribulose bisphosphate carboxylase activation level were inhibited in several mutants of the C(3) crucifer Arabidopsis thaliana which possess lesions in the photorespiratory pathway. This inhibition occurred when leaves were illuminated under a photorespiratory atmosphere (50% O(2), 350 microliters per liter CO(2), balance N(2)),

Rubisco Small Subunits’ Genome-Wide Identification and Their Function from Gene Expression to Rubisco Activity and Photosynthesis among Peanut Genotypes under Different Nitrogen Levels

open access: yesAgronomy, 2022
Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) is a critical protein for photosynthesis. With small subunits, RBCSs catalyze the fixation of CO2 onto ribulose-1,5-bisphosphate (RuBP).

Metabolic and molecular events occurring during chromoplast biogenesis [PDF]

open access: yes, 2011
Chromoplasts are nonphotosynthetic plastids that accumulate carotenoids. They derive from other plastid forms, mostly chloroplasts. The biochemical events responsible for the interconversion of one plastid form into another are poorly documented. However,
