National Engineering Research Centre of Edible Fungi, Key Laboratory of Applied Mycological Resources and Utilisation, Ministry of Agriculture, Institute of Edible Fungi, Shanghai Academy of Agriculture Sciences, Shanghai 201403, China

To systemically understand the biosynthetic pathways of bioactive substances, including triterpenoids and polysaccharides, in , the correlation between substrate degradation, carbohydrate and triterpenoid metabolism during growth was analyzed by combining changes in metabolite content and changes in related enzyme expression in over 5 growth phases. Changes in low-polarity triterpenoid content were correlated with changes in glucose and mannitol content in fruiting bodies. Additionally, changes in medium-polarity triterpenoid content were correlated with changes in the lignocellulose content of the substrate and with the glucose, trehalose and mannitol contents of fruiting bodies.

A.N. Belozersky Institute of Physico-Chemical Biology, Lomonosov Moscow State University, Moscow, Russia.

The light-induced functioning of photosynthetic pigment-protein complex of photosystem II (PSII) is linked to the vectorial translocation of charges across the membrane, which results in the formation of voltage. Direct measurement of the light-induced voltage (∆V) generated by spinach oxygen-evolving PSII core complexes adsorbed onto a Millipore membrane filter (MF) on an indium tin oxide (ITO) electrode under continuous illumination has been performed. PSII was shown to participate in electron transfer from water to the ITO electrode, resulting in ∆V generation. Read More

Trehalose protects Escherichia coli against carbon stress manifested by protein acetylation and aggregation.

Mol Microbiol 2019 09 19;112(3):866-880. Epub 2019 Jun 19.

Faculty of Biology, Department of General and Medical Biochemistry, University of Gdansk, Wita Stwosza 59, 80-308, Gdansk, Poland.

The disaccharide trehalose is widely distributed in nature and can serve as a carbon reservoir, a signaling molecule for controlling glucose metabolism and a stress protectant. We demonstrated that in Escherichia coli ΔotsA cells, which are unable to synthesize trehalose, the aggregation of endogenous proteins during the stationary phase was increased in comparison to wild-type cells. The lack of trehalose synthesis boosted Nε-lysine acetylation of proteins, which in turn enhanced their hydrophobicity and aggregation. Read More

Autophagy in Plants: Both a Puppet and a Puppet Master of Sugars.

Front Plant Sci 2019 22;10:14. Epub 2019 Jan 22.

Laboratory of Molecular Plant Biology, KU Leuven, Leuven, Belgium.

Autophagy is a major pathway that recycles cellular components in eukaryotic cells both under stressed and non-stressed conditions. Sugars participate both metabolically and as signaling molecules in development and response to various environmental and nutritional conditions. It is therefore essential to maintain metabolic homeostasis of sugars during non-stressed conditions in cells, not only to provide energy, but also to ensure effective signaling when exposed to stress.

ISIS Pulsed Neutron and Muon Source, STFC Rutherford Appleton Laboratory, Harwell Campus , Oxon, OX11 0QX, Oxfordshire, U.K.

The molecular structure of an aqueous solution of the disaccharide trehalose (CHO) has been studied by neutron diffraction and empirical potential structure refinement modeling. Six different isotope compositions with 33 wt % trehalose (corresponding to 38 water molecules per trehalose molecule) were measured to ensure that water-water, trehalose-water, and trehalose-trehalose correlations were accurately determined. In fact, this is the first neutron diffraction study of an aqueous trehalose solution in which also the nonexchangeable hydrogen atoms in trehalose are deuterated. Read More

Metabolite transport and associated sugar signalling systems underpinning source/sink interactions.

Biochim Biophys Acta 2016 10 31;1857(10):1715-25. Epub 2016 Jul 31.

Centre for Plant Sciences, School of Biology, Faculty of Biological Sciences, University of Leeds, Leeds LS2 9JT, UK. Electronic address:

Metabolite transport between organelles, cells and source and sink tissues not only enables pathway co-ordination but it also facilitates whole plant communication, particularly in the transmission of information concerning resource availability. Carbon assimilation is co-ordinated with nitrogen assimilation to ensure that the building blocks of biomass production, amino acids and carbon skeletons, are available at the required amounts and stoichiometry, with associated transport processes making certain that these essential resources are transported from their sites of synthesis to those of utilisation. Of the many possible posttranslational mechanisms that might participate in efficient co-ordination of metabolism and transport only reversible thiol-disulphide exchange mechanisms have been described in detail.
