Summary: In this study, the structure-activity relationship of the synthetic peptide LYGALGL derived from egg white was investigated using cell experiments and structure determination. The results showed that pulsed electric field treatment significantly increased the antioxidant activity of LYGALGL, leading to improved superoxide dismutase activity and mitochondrial membrane potential in cells, as well as decreased reactive oxygen species levels. Structure determination revealed that pulsed electric field treatment altered the structure of LYGALGL and exposed its active sites.

Summary: This study proposes a simple method to immobilize the functional peptide of GRGDS on the surface of SF films using GAGAGS sequences. This method does not involve any chemical reaction, preserving the original properties of SF molecules. The density of GRGDS peptides on GAGAGS-bound SF films was found to be higher compared to non-GAGAGS-bound films. Furthermore, the amount of immobilized (GAGAGS)GRGDS peptide increased with the promotion of β-sheet crystallization in the SF film. Fibroblasts adhered to the SF film showed increased extensibility due to (GAGAGS)GRGDS immobilization, indicating effective cell adhesion activity of RGD.

Summary: Selenopeptide Val-Pro-Arg-Lys-Leu-SeMet (Se-P1) demonstrates superior antioxidant and antineuroinflammatory effects compared to its native peptide Val-Pro-Arg-Lys-Leu-Met (P1). Se-P1 treatment also results in a more stable gut microbiota composition and a significant correlation with the alteration of metabolites. These findings have implications for the development of preventive or therapeutic strategies against neurodegenerative diseases and provide insights into selenopeptide nutrition and supplementation recommendations.

Summary: This study conducted theoretical research on the binding/activity of Leu-Pro-Arg-Asp-Ala (LPRDA) polypeptide with Sortase A (SrtA) of Staphylococcus aureus. The analysis of PDB structures and establishment of evaluation criteria for ligand-SrtA complex geometry, investigation of docking protocol, and molecular dynamics studies revealed that the binding of LPRDA with SrtA exaggerates the movement of specific parts of SrtA and makes it difficult to distinguish between different LPRDA-SrtA complex conformations.

Summary: This article presents the development of an atom-bond electronegativity equalisation method at the sigma pi-level (ABEEM) polarisable force field (PFF) for peptides. The ABEEM PFF utilises a fluctuating charge model to explicitly describe the polarisation effects in an extensive environment. Molecular dynamic simulations have been performed to examine the conformational properties of peptides in solution. Results show that the ABEEM PFF method is capable of accurately locating conformations and describing the energetics of peptides both in vacuo and aqueous solution.

Summary: DEAD-box helicases are important regulators of RNA-dependent cellular processes, with DbpA playing a role in ribosome maturation. By studying conformational changes of DbpA, researchers aim to better understand the ATP-dependent RNA unwinding process catalyzed by DEAD-box helicases. Initial NMR studies have provided insight into the structural dynamics of DbpA during its catalytic cycle.

Summary: The synthesized alpha-MoO3 and MoS2 NPs had nanosheet and nanoflower-like structures with different crystallite sizes. The uptake and bioaccumulation of Mo-NPs in rice seedlings were tissue-specific, and the impact of the nanoparticles showed stimulation of repair mechanisms at low doses but oxidative imbalance at higher concentrations. MoS2 NPs were found to be more environmentally safe compared to alpha-MoO3 NPs, with low translocation and accumulation with no significant impact on rice growth at 100 ppm concentration.
