Summary: This study investigates the molecular response mechanism of scallops to a combination of high temperature and hypoxia stress. The research reveals that scallops exhibit different sensitivities to environmental stress, and high temperature and hypoxia have a synergistic effect on scallops. Immune and apoptosis-related pathways play important roles in scallops' response to environmental stress, and heat shock proteins play a key role in scallops' adaptation to altered environments.

Summary: A new method for estimating transfer entropy in biomolecular systems was developed by analyzing the variance-covariance matrix of atomic fluctuations. The results showed systematic consistency of the method for calculating transfer entropy and provided insights into the interconnected residue networks in proteins. Additionally, evidence of possible allosteric activity and different paths of activation in mutants were presented, highlighting the important role of transfer entropy analysis in understanding allosteric behavior.

Summary: This article critically assesses the progress of the catalytic reaction of CH4 and CO2 to produce acetic acid, focusing on identifying and constructing active sites. The differences in metal oxidation state can affect the activation of CH4 and CO2, thereby changing the efficiency of the reaction. By modifying the active sites and transition states through metal site placement, framework environment, and acid site promotion, the efficiency of heterogeneous catalysts can be improved for this reaction.

Summary: mRNA packaging into germ granules is a conserved strategy for posttranscriptional regulation of germline mRNAs. We studied the homotypic clustering of nos and pgc in four Drosophila species and found that clustering is a conserved process that enriches germ granule mRNAs. Natural variations in nos 3ʹ UTR sequence influence clustering, resulting in decreased nos levels and increased defective germ cells. Our findings highlight the impact of evolution on germ granules and provide insight into the diversity and regulation of biomolecular condensates.

Summary: This study reanalyzed the structure of type I fatty acid synthases (FASs) and identified several differences in both structural and enzymatic domains between P. pastoris FAS and the prototypical yeast FAS from S. cerevisiae. By using focussed classification, the researchers were able to resolve and model the mobile acyl-carrier protein (ACP) domain, which is crucial for the function of FAS. The structure reported in this study will serve as a valuable resource for further engineering efforts to synthesize alternate products using yeast FAS.

Summary: This study describes azophenylindane based molecular motors, which have different rotamers in trans and cis configurations. The behaviors of these motors were investigated experimentally and computationally, revealing that the conversion of the motor results in a mixture of isomers. Some cis-rotamers can directly convert to each other, while others require conversion via trans-configuration. The motion of these motors is similar to a mixing machine, with the indane group acting as a base and the phenol group as a beater. These aphin-switches may have promising applications in advanced biological systems or in cases where molecular packing disordering is desired, such as lipid bilayers.

Summary: Membrane proteins are essential in molecular biology, but studying their structures requires finding suitable membranes and refolding protocols. Isotropic bicelles are commonly used as membrane mimetics, but the refolding process is still not well understood. To find the best refolding methods for helical membrane proteins, we studied the interactions between proteins, lipids, and detergents in trifluoroethanol-water mixtures. Using NMR spectroscopy and light scattering, we determined key states of the compounds and proposed optimal protocols. These protocols were tested on various membrane domains with successful results.

Summary: The synthesis of products from the interaction of 1,3-propanesultone ring with amides of pyridinecarboxylic acids was investigated. The position of the substituent in the heteroaromatic fragment and temperature condition influenced the yield of the reaction products. A mechanism and transition-state model were proposed based on spectroscopic, X-Ray, and quantum-chemical calculation data. The synthesized compounds showed promising pharmacological effects and low acute toxicity.

Summary: We report the NMR chemical shift assignment of FGF8b, an important regulator of brain embryonic development in humans. The obtained chemical shifts agree with X-ray data, except for the N-terminal gN helix which forms only when complexed with the receptor. This data serves as a starting point for investigating the interaction of FGF8b with its receptors and potential drugs or inhibitors.

Summary: In this study, we demonstrated that NanoLuc luciferase, a well-known enzyme, can serve as a fluorogen activating protein for arylidene-imidazolones analogs of the Kaede protein chromophore. We showed that these compounds can be utilized as fluorescent sensors for this particular protein and can also be employed alongside it as a genetically encoded tag in fluorescent microscopy.

Summary: Moliner et al. demonstrate that psychedelics can bind directly to the BDNF receptor TrkB and enhance its plasticity and antidepressant-like effects, while their hallucinogenic effects are unrelated to TrkB binding. These findings suggest that psychedelics have potential as fast-acting antidepressants with lasting effects, similar to clinically approved antidepressants. The study also reveals that LSD and psilocin have higher affinity for TrkB than other antidepressants, and both psychedelics and antidepressants bind to specific sites within the transmembrane domain of TrkB dimers.

Summary: Toll-like receptors (TLRs) play a crucial role in the innate immune system. In this study, the researchers investigated the spatial structures of the transmembrane and cytoplasmic juxtamembrane regions of TLR2, TLR3, TLR5, and TLR9 using solution NMR spectroscopy and computer simulations. They discovered a previously unreported structural element, the cytoplasmic hydrophobic juxtamembrane alpha-helix, which is important for receptor activation and serves as a more complex connection between the transmembrane and cytoplasmic parts of the proteins.

Summary: This study explains the ligand promiscuity of AstaPo1 by determining its NMR structure and validating it through various experiments. The FAS1 domain of AstaPo1 binds carotenoids by embracing their polyene structure, but cannot cap the beta-ionone rings to dictate specificity. This research also suggests the neofunctionalization of FAS1 in a subset of AstaP-like proteins in green algae.

Summary: In this study, three compounds were isolated and structurally elucidated from the Chaetomorpha linum algae. These compounds showed bioluminescence activity with Chaetopterus luciferase in the presence of Fe2+ ions. They are derivatives of polyunsaturated fatty acid peroxides. The study also confirmed the broad substrate specificity of the luciferase by obtaining and demonstrating the activity of their structural analogues in the bioluminescence reaction.
