Summary: In this study, a polyacrylonitrile nanofiber membrane functionalized with tris(hydroxymethyl)aminomethane was used as an affinity membrane for lysozyme adsorption in membrane chromatography. The dynamic adsorption behavior of lysozyme was investigated under various operating parameters, and the results showed that the pseudo-second-order kinetic model fitted well with the experimental data. The breakthrough curve characteristics were analyzed using different dynamic adsorption models, and the Yoon-Nelson model was found to be the best fit for the experimental data.

Summary: Tris-hydroxymethyl aminomethane (THAM) is an amino alcohol used clinically to buffer acid loads and raise pH in acidotic conditions. Available since 2020 in the United States, THAM may have clinical utility in managing acid-base derangements in conditions such as liver transplantation and acute respiratory distress syndrome (ARDS). However, clinical evidence supporting its use is limited, and high-quality evaluations are necessary.

Summary: High-resolution membrane protein structures are crucial for understanding cellular processes and drug discovery. Traditional detergents have limited stability, necessitating the development of novel agents for membrane protein structural study. The designed TTGs showed improved stability of membrane proteins compared to maltoside detergents, likely due to their high hydrophobicity, optimal hydrophilic-lipophilic balance, and absence of cis-trans isomerism.

Summary: In order to overcome the practical stability and efficiency problems of tin-based perovskite solar cells (PSCs), researchers added a passivation material THAM into the formamidinium tin iodide (FASnI(3))perovskite, which improved light absorption ability and film crystallinity while inhibiting the oxidation of Sn2+. PSCs with THAM-doped FASnI(3) perovskite films achieved a high power conversion efficiency of 9.18%. Furthermore, the storage stabilities of PSCs were significantly prolonged, with 85% of initial efficiency maintained for 550 hours in an N-2 environment.

Summary: Dynamic allosteric regulation refers to a type of regulation that does not involve noticeable conformational changes. By developing a unified anisotropic elastic network model, the contribution of pure dynamic allosteric regulation was quantitatively estimated. The study found that pure dynamic allosteric regulation has a generally small contribution, which decays exponentially with the distance between the substrate and the allosteric ligand. Toy models were also used to analyze the factors determining dynamic allosteric regulation in proteins.

Summary: This study demonstrates the importance of protein topology in allosteric regulation, showing that allosteric proteins mainly have multiple domains or subunits, and allosteric sites are often located between domains of the same fold type. A novel method, called TopoAlloSite, was developed to predict the location of allosteric sites on protein topology, successfully identifying cryptic allosteric sites in several proteins. This research provides insights for finding new druggable targets and designing allosteric drugs.

Summary: Allostery plays a fundamental role in biological processes, but predicting the impact of allosteric mutations, modifications, and effector binding on protein function is challenging. We developed a novel computational method, KeyAlloSite, to predict allosteric sites and identify key allosteric residues based on the evolutionary coupling model. Our predictions are consistent with previous experimental studies and key cancer mutations. KeyAlloSite can be applied in studying the evolution of protein allosteric regulation, designing and optimizing allosteric drugs, and performing functional protein design and enzyme engineering.

Summary: Loop epitopes at protein-protein binding interfaces are underexplored as drug targets due to their high flexibility, relatively few hot spots, and solvent accessibility. However, this study demonstrates that cyclic peptides derived from loop epitopes can inhibit protein activity by directly binding to the dimer interface and disrupting the oligomer formation. These findings suggest that rationally designed cyclic peptides can modulate protein oligomers and be used to design inhibitors for other seemingly intractable oligomeric proteins.
