Evolutionary history expands the range of signaling interactions in hybrid multikinase networks

Anne-Florence Raphaëlle Bitbol, Mohamed Barakat

Two-component systems (TCSs) are ubiquitous signaling pathways, typically comprising a sensory histidine kinase (HK) and a response regulator, which communicate via intermolecular kinase-to-receiver domain phosphotransfer. Hybrid HKs constitute non-canonic ...

An Isoprene Lipid-Binding Protein Promotes Eukaryotic Coenzyme Q Biosynthesis

Matteo Dal Peraro, Deniz Aydin

The biosynthesis of coenzyme Q presents a paradigm for how cells surmount hydrophobic barriers in lipid biology. In eukaryotes, CoQ precursors-among nature's most hydrophobic molecules-must somehow be presented to a series of enzymes peripherally associate ...

Protection Group Effects During α,γ-Diol Lignin Stabilization Promote High-Selectivity Monomer Production

Jeremy Luterbacher, Masoud Talebi Amiri, Christopher Marc Hunston, Wu Lan

Protection groups were introduced during biomass pretreatment to stabilize lignin's α,γ-diol group during its extraction and prevent its condensation. Acetaldehyde and propionaldehyde stabilized the α,γ-diol without any aromatic ring alkylation, which sign ...

Chromate Resistance Mechanisms in Leucobacter chromiiresistens

Rizlan Bernier-Latmani, Elena Suvorova Buffat

Chromate is one of the major anthropogenic contaminants on Earth. Leucobacter chromiiresistens is a highly chromate-resistant strain, tolerating chromate concentrations in LB medium of up to 400 mM. In response to chromate stress, L. chromiiresistens forms ...

Source apportionment of organic carbon in Centreville, AL using organosulfates in organic tracer-based positive matrix factorization

Athanasios Nenes, Hairun Guo

Organic tracer-based positive matrix factorization (PMF) was used to apportion fine particulate (PM2.5) organic carbon (OC) to its sources in Centreville, AL, USA, a rural forested site influenced by anthropogenic emissions, during the Southern Oxidant and ...

Maternal allocation of carotenoids increases tolerance to bacterial infection in brown trout

Laure Menin, Matay Hobil

Life-history theory predicts that iteroparous females allocate their resources differently among different breeding seasons depending on their residual reproductive value. In iteroparous salmonids there is typically much variation in egg size, egg number, ...

Extraction of carotenoids from Chlorella vulgaris using green solvents and syngas production from residual biomass

Christof Holliger, Christian Ludwig, Shivom Sharma, Jean-Paul Schwitzguebel, Dominik Refardt

A combined process for carotenoids extraction and efficient bioenergy recovery from the wet microalgae biomass is proposed. High added-value products could thus be extracted prior a hydrothermal gasification of the algal biomass into synthetic natural gas. ...

Product diversification in the sugarcane biorefinery through algae growth and supercritical CO 2 extraction: Thermal and economic analysis

François Maréchal, Adriano Viana Ensinas

The sugarcane sector in Brazil has undergone a major modernization in the last thirty years. Embracing the biorefinery concept, this sector is investigating bioproduct diversification and mostly putting a lot of effort and investment on second generation e ...

Photoacclimatory and photoprotective responses to cold versus heat stress in high latitude reef corals

Thomas Krüger

Corals at the world's southernmost coral reef of Lord Howe Island (LHI) experience large temperature and light fluctuations and need to deal with periods of cold temperature (< 18 °C), but few studies have investigated how corals are able to cope with thes ...

Classical Force Fields Tailored for QM Applications: Is It Really a Feasible Strategy?

Oliviero Andreussi

Classical molecular dynamics is more and more often coupled to quantum mechanical based techniques as a statistical tool to sample configurations of molecular systems embedded in complex environments. Nonetheless, the classical potentials describing the mo ...
