Microbial communities in dark oligotrophic volcanic ice cave ecosystems of Mt. Erebus, Antarctica. [PDF]

open access: yes, 2015
The Earth's crust hosts a subsurface, dark, and oligotrophic biosphere that is poorly understood in terms of the energy supporting its biomass production and impact on food webs at the Earth's surface.

The effect of exogenous factors on the polyenzymatic activity of RuBisCO and ATP synthase of chloroplasts from pea leaves

open access: yesЖурнал органічної та фармацевтичної хімії, 2021
Aim. To isolate and purify protein complexes – ATP synthase and RuBisCO – from pea leaf chloroplasts and study the effect of a microbiological fertilizer “Extracon” and sulfonamide inhibitors acetazolamide and ethoxyzolamide on the enzymatic activity of ...

Augmenting the Calvin-Benson-Bassham cycle by a synthetic malyl-CoA-glycerate carbon fixation pathway. [PDF]

open access: yes, 2018
The Calvin-Benson-Bassham (CBB) cycle is presumably evolved for optimal synthesis of C3 sugars, but not for the production of C2 metabolite acetyl-CoA.

Changes in Soluble Protein Profile in Cotton Leaves Indicate Rubisco Damage after Treatment with Sumi-Alpha Insecticide

open access: yesAgriculture, 2020
The cotton plant suffers from many pests and due to its economic importance, the use of efficient but ecologically friendly pesticides is highly desirable.

Effects of introduction of sorghum RbcS with rice RbcS knockdown by RNAi on photosynthetic activity and dry weight in rice

open access: yesPlant Production Science, 2021
Rubisco is the key enzyme responsible for photosynthetic CO2 fixation. Previously, we succeeded to increase the catalytic rate (kcat) of Rubisco by the overexpression of sorghum C4-type Rubisco small subunit (RbcS) in rice. These Rubisco are present as a

Photosynthetic Adaptation to Length of Day Is Dependent on S-Sulfocysteine Synthase Activity in the Thylakoid Lumen [PDF]

open access: yes, 2012
Arabidopsis (Arabidopsis thaliana) chloroplasts contain two O-acetyl-serine(thiol)lyase (OASTL) homologs, OAS-B, which is an authentic OASTL, and CS26, which has S-sulfocysteine synthase activity.

Amino Acids Sequence Based in Silico Analysis of RuBisCO (Ribulose-1,5 Bisphosphate Carboxylase Oxygenase) Proteins in Some Carthamus L. ssp.

open access: yesNotulae Scientia Biologicae, 2017
RuBisCO is an important enzyme for plants to photosynthesize and balance carbon dioxide in the atmosphere. This study aimed to perform sequence, physicochemical, phylogenetic and 3D (three-dimensional) comparative analyses of RuBisCO proteins in the ...

Rubisco Function, Evolution, and Engineering

open access: yesAnnual Review of Biochemistry, 2023
Carbon fixation is the process by which CO2 is converted from a gas into biomass. The Calvin–Benson–Bassham cycle (CBB) is the dominant carbon-consuming pathway on Earth, driving >99.5% of the ∼120 billion tons of carbon that are converted to sugar by plants, algae, and cyanobacteria.

Activation of interspecies-hybrid Rubisco enzymes to assess different models for the Rubisco–Rubisco activase interaction

open access: yesPhotosynthesis Research, 2013
Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) is prone to inactivation from non-productive binding of sugar-phosphates. Reactivation of Rubisco requires conformational remodeling by a specific chaperone, Rubisco activase. Rubisco activase from tobacco and other plants in the family Solanaceae is an inefficient activator of Rubisco from non ...

Function, Structure, and Evolution of the RubisCO-Like Proteins and Their RubisCO Homologs [PDF]

open access: yesMicrobiology and Molecular Biology Reviews, 2007
SUMMARYAbout 30 years have now passed since it was discovered that microbes synthesize RubisCO molecules that differ from the typical plant paradigm. RubisCOs of forms I, II, and III catalyze CO2fixation reactions, albeit for potentially different physiological purposes, while the RubisCO-like protein (RLP) (form IV RubisCO) has evolved, thus far at ...
