Summary: In this study, an artificial protein cage was created to house a dual-metal-tagged guest protein. The guest protein, consisting of a fusion protein of HaloTag and monomeric rhizavidin, catalyzed a linear, two-step sequential cascade reaction. The protein capsid encapsulated a ruthenium-catalyzed deprotection reaction followed by a gold-catalyzed hydroamination reaction, resulting in the production of indoles and phenanthridines with up to 66% overall yield in aqueous solutions. Additionally, the encapsulation of the guest protein stabilized the metal catalysts against deactivation by air, proteins, and cell lysate.

Summary: This study introduces a novel synthetic route to prepare heterobimetallic compounds incorporating Pt(II) diyne and polyine with 5,5'- and 6,6'-disubstituted 2,2'-bipyridines. The incorporation of Re(CO)(3)Cl pendant functionality in these compounds has a synergistic effect on the optical properties, resulting in red shifting of absorption and strong long-wavelength absorptions. Computational modeling revealed that 5,5'-disubstituted 2,2'-bipyridine systems are better candidates due to higher yield, improved photophysical properties, and stability compared to their 6,6'-substituted counterparts.

Summary: This study presents a self-assembly approach to fabricating protein origami with a networklike structure by designing dual noncovalent interactions on the different positions of a single protein building block. The approach involves constructing 1D protein filaments through metal coordination and creating network superstructures through cross-linking of the filaments at branch point linkages using pi-pi stacking interactions. The resulting protein networks exhibit reversible, injectable, and self-healing properties and can promote bone regeneration.

Summary: A new sequential metalation strategy has been developed for the assembly of a more stable heterobimetallic [PdPtL4](4+) cage. By using a low-symmetry ditopic ligand (L) with imidazole and pyridine donor units, a [Pt(L)(4)](2+) open-cage complex was selectively formed and then reacted with Pd(ii) ions to assemble the cage C. Various spectroscopy and crystallography techniques confirmed the formation of the cage and its heterobimetallic structure. The cage C exhibited anionic guest molecule binding capability and demonstrated stimulus-responsive behavior.

Summary: Dynamic foldamers, synthetic folded molecules that can change conformation in response to external stimulus, are leading the field of foldamer chemistry. This study presents a size-and shape-switching small dynamic covalent foldamer network that responds to changes in pH. Acidic conditions lead to the oligomerization of a dipeptide-based building block into a 16 subunit macrocycle, while higher pH yields a smaller cyclic foldamer. Both foldamers can readily interconvert upon adjusting the pH. The ability to access multiple discrete foldamers from a single building block is unique and promising for the development of foldamers with adaptive behavior.

Summary: Apoptosis is regulated by the BCL-2 family, and inhibition of the pro-apoptotic and anti-apoptotic protein-protein interactions has been studied for developing anticancer drugs. In this study, the hydrophobic nature of 74 organometallic compounds was analyzed, and their effectiveness against the BCL-2 protein was determined using molecular docking. The results identified several important compounds that could bind to the less solvent-accessible site of BCL-2.

Summary: In this study, the synthesis, characterization, and electrocatalytic CO2 reduction activity of a series of Pd-(II) complexes supported by tetradentate pyridinophane ligands are reported. Specifically, the electrocatalytic CO2 reduction activity of a Pd-(II) complex supported by the mixed hard--soft donor ligand 2,11-dithia[3.3]-(2,6)-pyridinophane (N2S2) is focused. Spectroscopic evidence of a CO-induced decomposition pathway for the same catalyst is also provided, which sheds light on catalyst poisoning for molecular Pd CO2 reduction electrocatalysts.

Summary: In this study, a novel 2D covalent triazine framework (CTF) was prepared for the immobilization of Ru(p-Cymene)Cl-2, obtaining a heterogeneous catalyst for formaldehyde decomposition. It was found that formaldehyde and water undergo a transformation reaction to produce formic acid and hydrogen, and then formic acid further decomposes to generate hydrogen and carbon dioxide. This work proposed a new method for organometallic immobilization and hydrogen production from formaldehyde decomposition.

Summary: Unlike other viruses, Cypoviruses have a doubly protected genome due to being embedded in a perfect polyhedrin crystal. A symmetry-based approach is proposed to predict the interface structure between the capsids and the crystal. The study reveals a remarkable match between the surfaces of Cypovirus and the polyhedrin matrix, highlighting the important role of VP5 proteins in embedding the virus and discussing the relationship between protein activity and superstructure formation.

Summary: In this study, a hierarchical protein assembly system with two distinct protein-protein interaction sites was constructed using an anisotropic-shaped protein needle. High-speed atomic force microscopy measurements showed the formation of unique tetrameric clusters through the N-terminal head of the protein on a mica surface. These clusters further self-assembled into a monolayer structure through the C-terminal His-tag. The results expand the toolbox for constructing hierarchical protein assemblies based on structural anisotropy.

Summary: This study investigates the impact of aromatic clusters on protein stability by studying designed aromatic interactions within a protein cage. The results show that inter-subunit phenylalanine clusters enhance interhelix interactions and increase melting temperature. Theoretical calculations suggest that this is due to a transformation from T-shaped geometry to pi-pi stacking and hydration entropic gain at high temperatures. The isolated nanoenvironment within a protein cage allows for detailed analysis of multiple clustering residues, providing insights into biomolecular interactions and potential applications in bionanomaterial design.

Summary: The emergence of protein-based crystalline materials provides promising opportunities for enzyme immobilization. This study demonstrates the use of polyhedra crystals to simultaneously encapsulate the foreign enzymes FDH and the organic photocatalyst eosin Y. These hybrid protein crystals, prepared easily by cocrystallization within a cell, form solid particles at a scale of 1 μm without the need for complex purification processes. The immobilized FDH within protein crystals exhibits recyclability, thermal stability, and maintains 94.4% activity compared to the free enzyme. Additionally, the incorporation of eosin Y enables CO(2)-formate conversion activity in the solid catalyst through a cascade reaction. This work highlights the potential of engineering protein crystals for the development of robust and environmentally friendly solid catalysts for artificial photosynthesis.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
