Direct catalytic conversion of methane to methanol offers a pathway for transforming a potent greenhouse gas into a portable clean liquid fuel, thereby mitigating carbon emissions and supporting sustainable energy. However, this process faces challenges from thermodynamically favorable methanol overoxidation. Here, we show that spatiotemporal regulation of photogenerated charge carriers on enginee

β-Alanine synthase (βAS), which is a dizinc metalloenzyme, catalyzes the irreversible hydrolysis of N-carbamyl-β-alanine (NCβA) to β-alanine. This enzyme has potential applications for β-amino acid production. Understanding the reaction mechanism and selectivity of βAS at atomic details can help design and engineer the enzyme for cascade biocatalysis. Here, the protonation states of two conserved

Cytokines play an important role in the regulation of homeostasis and inflammation. A de-regulated cytokine function can subsequently promote chronic inflammation. This is supported by clinical evidence showing the beneficial effect of inhibiting TNF-alpha through injection of antibodies and soluble receptor in disorders such as rheumatoid arthritis and Crohn's disease. Systemic anti-TNF-alpha the

The World Meteorological Organization (WMO) Global Atmosphere Watch (GAW) coordinates high-quality atmospheric greenhouse gas observations globally and provides these observations through the WMO World Data Centre for Greenhouse Gases (WDCGG) supported by Japan Meteorological Agency. The WDCGG and the National Oceanic and Atmospheric Administration (NOAA) analyse these measurements using different

Organophosphate hydrolases are proficient catalysts of the breakdown of neurotoxic organophosphates and have great potential as both biotherapeutics for treating acute organophosphate toxicity and as bioremediation agents. However, proficient organophosphatases such as serum paraoxonase 1 (PON1) and the organophosphate-hydrolyzing lactonase SsoPox are unable to hydrolyze bulkyorganophosphates with

Despite the abundance of membrane-associated enzymes, the mechanism by which membrane binding stabilizes these enzymes and stimulates their catalysis remains largely unknown. Serum paraoxonase-1 (PON1) is a lipophilic lactonase whose stability and enzymatic activity are dramatically stimulated when associated with high-density lipoprotein (HDL) particles. Our mutational and structural analyses, co

Monoamine oxidase (MAO), which exists in two isozymic forms, MAO A and MAO B, is an important flavoenzyme responsible for the metabolism of amine neurotransmitters such as dopamine, serotonin, and norepinephrine. Despite extensive research effort, neither the catalytic nor the inhibition mechanisms of MAO have been completely understood. There has also been dispute with regard to the protonation s

This article traces the flow of municipal solid waste from southern Italy through a waste‐to‐energy facility and district heating system in Austria, examining the roles that waste's transformation from contaminant to commodity to fuel plays in interconnected, distributed, and contested urbanization processes. It contends that, while metabolic circulation hides socioecological costs in one place to

Mount Lovćen holds significant cultural, political and religious symbolism in Montenegro, especially due to the fact that the mountain is the last resting place of the prince-bishop and national poet Petar II Petrovich-Njegoš (1813–1851). In the twentieth century the grave of Njegoš has undergone profound material transformations. Each of these transformations has led to heated debates about the s
