Microorganisms are essential for life on Earth, performing key roles in numerous biological processes. Their influence extends across a wide spectrum, from human health and ecological balance to advancements in biotechnology and industrial applications. Th ...

Assigning or proposing a catalysing enzyme given a chemical or biochemical reaction is of great interest to life sciences and chemistry alike. The exploration and design of metabolic pathways and the challenge of finding more sustainable enzyme-catalysed a ...

This work demonstrated that consolidated bioprocessing is a promising concept for conversion of lignocellulose to ethanol at industrial scale. CBP offers great cost saving potential, is feasible to be operated continuously and may be scaled up due to exten ...

The metabolic capabilities of the species and the local environment shape the microbial interactions in a community either through the exchange of metabolic products or the competition for the resources. Cells are often arranged in close proximity to each ...

Plant specialized metabolites play an important role in soil carbon (C) and nutrient fluxes. Through anti-microbial effects, they can modulate microbial assemblages and associated microbial-driven processes, such as nutrient cycling, so to positively or ne ...

Accurate determination of physiological states of cellular metabolism requires detailed information about metabolic fluxes, metabolite concentrations and distribution of enzyme states. Integration of fluxomics and metabolomics data, and thermodynamics-base ...

Mono layer graphene field-effect sensors operating in liquid have been widely deployed for detecting a range of analyte species often under equilibrium conditions. Here we report on the real-time detection of the binding kinetics of the essential human enz ...

Tryptophan metabolites in the kynurenine pathway are up-regulated by pro-inflammatory cytokines or glucocorticoids, and are linked to anti-inflammatory and immunosuppressive activities. In addition, they are up-regulated in pathologies such as cancer, auto ...

Changes in riparian vegetation or water turbidity and browning in streams alter the local light regime with potential implications for stream biofilms and ecosystem functioning. We experimented with biofilms in microcosms grown under a gradient of light in ...

When introduced into the aquatic environment, TiO2 NP are likely to settle from the water column, which results in increased exposure of benthic communities. Here, we show that the activity of two extracellular enzymes of intact heterotrophic biofilms, bet ...

Metal complexes are increasingly being used to inhibit enzymes. The reasons for this increased interest arise from the special features that metal complexes offer, e.g. the facile construction of 3D architectures that tightly fill enzyme active sites incre ...

A comparison between engineered and commercially available L-lactate oxidases from Aerococcus viridans was conducted for biosensing applications. Enzymes were adsorbed onto the surfaces of graphite electrodes modified with multi-walled carbon nanotubes. Th ...

Reductive dehalogenases are the key enzymes involved in the anaerobic respiration of organohalides such as the widespread groundwater pollutant tetrachloroethene. The increasing number of available bacterial genomes and metagenomes gives access to hundreds ...

Platinum-based cancer drugs, such as cisplatin, are highly effective chemotherapeutic agents used extensively for the treatment of solid tumors. However, their effectiveness is limited by drug resistance, which, in some cancers, has been associated with an ...

A series of bimetallic titanium-ruthenium complexes of general formula (η5-C5H5)(μ-η5:κ1-C5H4(CR12)nPR2R3)TiCl2RuCl2 (n = 0, 1, 2 or 4; R1 = H or Me; R2 = H, Ph, or Cy; R3 = Ph or Cy) have been synthesized, including two novel compds. as wel ...

Respiration is a fundamental catalytic process in the aerobic and anaerobic energy metabolism of many prokaryotic and most eukaryotic organisms. The major difference between these organisms is that various organic and inorganic substrates can be used to do ...

A novel reactive perstraction system has been developed based on liq.-core capsules, involving an enzyme-catalyzed reaction coupled with simultaneous in situ product recovery. Lipase-catalyzed reactions, hydrolysis of triprionin and nitrophenyl laurate, we ...

The preparation of oligoribonucleotides is of great interest for structural and functional investigations in biomolecular chemistry and biology. Relevant RNAs are relatively long and contain often modifications. Two methods for their preparation are curren ...
