Summary: The study shows that myristoylation alone can be sufficient for significant membrane association, concentrating PKA activity and regulating AMPA receptors at neuronal synapses. While membrane affinity of PKA-C can be tuned by charges near the myristoylation site, the net neutral charge of PKA-C N terminus is evolutionally conserved.

Summary: This study constructed transformed strains to investigate the role of GNAI gene in the growth and development of Pleurotus eryngii. The expression of GNAI was found to affect mycelial growth and clamp connection number. Transformed strains exhibited higher endogenous cAMP levels, affecting amylase and laccase activity. GNAI expression was also associated with primordia formation and button number in P. eryngii.

Summary: In this study, CZ with increasing rc-Ce2Zr2O8 content was synthesized by increasing reduction time, and the influence of rc-Ce2Zr2O8 content on TWC performance was investigated. It was found that 19.8% rc-Ce2Zr2O8 could significantly improve the reducibility of CZ and enhance the catalytic activity of TWCs. Therefore, constructing a larger crystal interface between rc-Ce2Zr2O8 and the cubic-phase matrix is more efficient than increasing the rc-Ce2Zr2O8 content by consuming huge energy for improving TWC performance.

Summary: This study reports the structure of a bacterial PmrA-dependent transcription activation complex, which reveals that RNAPH interacts with the C-terminal DNA-binding domain of PmrA via electrostatic interactions and reorients the DBD, resulting in a dynamic TAC conformation. In vivo assays show that substitution of the DNA-recognition residue eliminates its transcriptional activity, while variants with altered RNAPH-interacting residues result in enhanced transcriptional activity. These findings suggest the importance of both PmrA recognition-induced DNA distortion and promoter escape in its transcriptional activation.

Summary: In this study, we investigated the effect of vertex correction on spin pumping from a ferromagnetic insulator (FI) into a two-dimensional electron gas (2DEG) with both Rashba and Dresselhaus spin-orbit interactions. We found that the Gilbert damping due to elastic spin-flipping is significantly enhanced by the vertex correction when the ratio of the two spin-orbit interactions is near a special value, while the damping due to magnon absorption shows only minor modification. Additionally, we observed a strong enhancement in the resonant frequency shift caused by elastic spin-flipping, similar to the Gilbert damping.

Summary: Supports can regulate the atomic geometry and electronic structures of active sites at the interface, thus affecting the catalytic activity and selectivity of nanoparticles. In this study, we constructed the Co3O4/TiO2 interface to enhance the catalytic decomposition of ammonium perchlorate (AP). Experimental and theoretical studies revealed that Co3O4 nanoparticles can strongly anchor onto TiO2 supports with charge transfer, leading to enhanced NH3 adsorption through hydrogen bonds at the interface. These findings provide new insights into the promotion effects of the nanoparticle/support system on the AP decomposition process and inspire efficient catalyst design.

Summary: Controlled degradation of proteins is crucial for maintaining a healthy proteome. A family of proteins called Catalytic Core Regulators (CCRs) has been discovered to regulate the function of the 20S proteasome through an allosteric mechanism. The physical binding of the PSMB4 subunit attenuates the proteolytic activities of the proteasome. This finding sheds light on a novel allosteric pathway that can be targeted for developing selective 20S proteasome inhibitors and uncoupling the degradation pathways of 20S and 26S proteasomes.

Summary: Noble metal Pt nanocatalysts with unique triple-junction structure exhibit enhanced catalytic stability and high activity for CO oxidation at mild temperatures, attributed to electron donation from graphitized carbon and confinement effect from high-density nanopores of the CeO2 support. Triple-junction Pt-C-CeO2 structure provides new inspiration for high-performance nanocatalyst fabrication.

Summary: In this study, a heterogeneous catalyst composed of ultrafine CuOx on Co3O4 prepared by co-precipitation exhibited promising low-temperature activity and good water resistance for the oxidation of toluene and CO. The Cu(I)-O-Co interface was found to play a crucial role in promoting catalytic oxidation and reducing the accumulation of unwanted species on the catalyst surface, demonstrating comparable performance to partial supported noble metal catalysts.

Summary: The G beta-like protein gene Bcgbl1 in the gray mold fungus Botrytis cinerea regulates development and pathogenicity by interacting with the adapter protein of the cascade of MAP kinases (MAPK) and affecting phosphorylation levels of two MAPKs. Bcgbl1 is also involved in cell wall integrity, oxidative stress tolerance, and gene expression. Three target genes encoding hydrophobic surface binding proteins contribute to the adhesion and virulence of B. cinerea.

Summary: Catalytic combustion is an advanced technology used to eliminate industrial volatile organic compounds. By designing homogeneous interfaces, a mesocrystalline CeO2 catalyst with abundant Ce-Ce homogeneous interfaces was synthesized and showed enhanced catalytic performance for toluene combustion. The abundant Ce-Ce homogeneous interfaces formed by highly ordered stacking and small grain size endow the CeO2 mesocrystal with superior redox property and oxygen storage capacity.
