• Nitrous oxide production via enzymatic nitroxyl from the nitrifying archaeon Nitrosopumilus maritimus AI翻译

  摘要：Ammonia oxidizing archaea (AOA) are among the most abundant microorganisms on earth and are known to be a major source of nitrous oxide (N2O) emissions, although biochemical origins of this N2O remain unknown. Enzymological details ofAOA nitrogen metabolism are broadly unavailable. We report the recombinant expression, purification, and characterization of a multicopper oxidase, Nmar_1354, from the AOA Nitrosopumilus maritimus. We show that Nmar_1354 selectively produces nitroxyl (HNO) by coup...

  摘要：The SWItch/Sucrose Non- Fermenting (SWI/SNF) complexes are evolutionarily con-served, ATP- dependent chromatin remodelers crucial for multiple nuclear functions in eukaryotes. Recently, plant BCL- DOMAIN HOMOLOG (BDH) proteins were identified as shared subunits of all plant SWI/SNF complexes, significantly impacting chromatin accessibility and various developmental processes in Arabidopsis. In this study, we performed a comprehensive characterization of bdh mutants, revealing the role of BDH i...
• Resolving electrochemically triggered topological defect dynamics and structural degradation in layered oxides AI翻译

  摘要：Understanding topological defects- controlled structural degradation of layered oxides-a key cathode material for high- performance lithium- ion batteries-plays a critical role in developing next- generation cathode materials. Here, by constructing a nanobattery in an electron microscope enabling atomic- scale monitoring of electrochemcial reactions, we captured the electrochemically driven atomistic dynamics and evolution of dislocations-a most important topological defect in material. We dec...

• The Aedes aegypti mosquito evolves two types of prophenoloxidases with diversified functions AI翻译

  摘要：Insect phenoloxidase, presented as an inactive precursor prophenoloxidase (PPO) in hemolymph, catalyzes melanin formation, which is involved in wound healing, pathogen killing, reversible oxygen collection during insect respiration, and cuticle and eggshell formation. Mosquitoes possess 9 to 16 PPO members across different genera, a num-ber that is more than that found in other dipteran insects. However, the reasons for the redundancy of these PPOs and whether they have distinct biochemical pr...

• Olfaction with legs-Spiders use wall- pore sensilla for pheromone detection AI翻译

  摘要：The sense of smell is a central sensory modality of most terrestrial species. However, our knowledge of olfaction is based on vertebrates and insects. In contrast, little is known about the chemosensory world of spiders and nothing about how they perform olfaction despite their important ecological role. The orb-weaving spider Argiope bruennichi lends itself to an in-depth study on olfaction as it is one of the few spider species whose volatile sex pheromone, emitted by females to attract male...
• Assembly-enhanced recognition: A biomimetic pathway to achieve ultrahigh affinities AI翻译

  摘要：On the one hand, nature utilizes hierarchical assemblies to create complex biological binding pockets, enabling ultrastrong recognition toward substrates in aqueous solutions. On the other hand, chemists have been fervently pursuing high-affinity recognition by constructing covalently well-preorganized stereoelectronic cavities. The potential of noncovalent assembly, however, for enhancing molecular recognition has long been underestimated. Inspired by (strept)avidin, an amphiphilic azocalix[4...
