Sulfide as a signaling molecule in autophagy
(Taylor & Francis, 2013)
Hydrogen sulfide is already recognized as an important signaling molecule in mammalian systems, and emerging data suggest that H2S is a signaling molecule just as important as nitric oxide (NO) and H2O2 in plants. Although ...

Dynamics of the Intrinsically Disordered Inhibitor IF7 of Glutamine Synthetase in Isolation and in Complex with its Partner
(Elsevier, 2020)
Glutamine synthetase (GS) catalyzes the ATP-dependent formation of glutamine from glutamate and ammonia. The activity of Synechocystis sp. PCC 6803 GS is regulated, among other mechanisms, by protein-protein interactions ...

Insights into the function of NADPH thioredoxin reductase C (NTRC) based on identification of NTRC-interacting proteins in vivo
(Oxford University Press, 2019)
Redox regulation in heterotrophic organisms relies on NADPH, thioredoxins (TRXs), and an NADPH-dependent TRX reductase (NTR). In contrast, chloroplasts harbor two redox systems, one that uses photoreduced ferredoxin (Fd), ...

Haloferax mediterranei Cells as C50 Carotenoid Factories
(MDPI, 2021)
Haloarchaea produce C50 carotenoids such as bacterioruberin, which are of biotechnological in-terest. This study aimed to analyze the effect of different environmental and nutritional conditions on the cellular growth and ...

Manipulating photorespiration to increase plant productivity: recent advances and perspectives for crop improvement.
(Marion Eisenhut, 2016)
Recycling of the 2-phosphoglycolate generated by the oxygenase reaction of Rubisco requires a complex and energy-consuming set of reactions collectively known as the photorespiratory cycle. Several approaches aimed at ...

Compartmentalization, a key mechanism controlling the multi-tasking role of SnRK1 complex
(Oxford University Press, 2022)
SNF1-related protein kinase 1 (SnRK1), the plant ortholog of mammalian AMP-activated protein kinase/fungal (yeast) Sucrose Non-Fermenting 1 (AMPK/SNF1), plays a central role in metabolic responses to reduced energy levels ...

Recalcitrant carbohydrates after enzymatic hydrolysis of pretreated lignocellulosic biomass
(BioMed Central, 2016)
Background To reduce the cost of the enzymes for the hydrolysis of lignocellulosic biomass, two main strategies have been followed: one, the reduction of enzyme dosing by the use of more efficient and stable enzymatic ...

Evolution of photoperiod sensing in plants and algae
(Elsevier, 2017)
Measuring day length confers a strong fitness improvement to photosynthetic organisms as it allows them to anticipate light phases and take the best decisions preceding diurnal transitions. In close association with ...

Purification of Starch Granules from Arabidopsis Leaves and Determination of Granule-Bound Starch Synthase Activity
(Bio-Protocol, 2014)
Starch constitutes the most important carbon reserve in plants and is composed of branched amylopectin and linear amylose. The latter is synthesized exclusively by the Granule-Bound Starch Synthase (GBSS, EC 2.4.1.21). ...

Assessing the transcriptional regulation of L-cysteine desulfhydrase 1 in Arabidopsis thaliana
(Frontiers Media, 2014)
Hydrogen sulfide is an important signaling molecule that functions as a physiological gasotransmitter of comparable importance to NO and CO in mammalian systems. In plants, numerous studies have shown that sulfide increases ...
