Summary: Photosynthesis, powered by sunlight, is crucial for the survival of most life forms. The light-driven electron transfer at photosystem I generates important reducing power at the cellular level, determining the total global enthalpy in living systems. Studying the structure of photosynthetic machinery is essential for understanding its mode of action.

Summary: Redox logic materials provide new approaches to modulate intracellular pathologic redox environment in specific areas, but the unambiguity and repetitive switchability of redox logic states are difficult to achieve. A multistable coordination polymer (CP) was constructed by combining a bistable diisophthalic phenazine dye ligand with Cu-II salt, and its dye-Cu anisotropic junction achieved diode-like unidirectional electron transfer and logic state ratchet for the first time. The radical cationic CP remained in the OFF state with low toxicity in healthy tissues, but was reduced to the neutral SERVO state by overexpressed glutathione (GSH) in hypoxic tumors. After photoirradiation, the stabilized charge-separated ON state promoted photo-Fenton reaction for reactive oxygen species (ROS) signal transduction, while simultaneously recovering the initial state for catalytic signal amplification of ROS, providing intratumor redox photomodulation for therapy.

Summary: Heavy metals like Cd pose environmental problems and threats to various organisms. This study investigated the effects of Cd on the growth and activities of PSI and PSII in Chlorella pyrenoidosa. The results showed that Cd had a more severe inhibition on PSII than on PSI. Cd decreased the efficiency of PSII's energy utilization under high light. However, the quantum yield of PSI did not show significant differences among different Cd treatments. Activation of CEF played a crucial role in the induction of NPQ. The binding features of Cd ions and photosystem particles suggested that Cd had a stronger affinity for PSII than for PSI.

Summary: A biohybrid electronic system has been developed with a photosystem I (PSI) fixed on a porous antimony-doped tin oxide electrode, resulting in light-powered reduction of NADPH. Cytochrome c was used to orient PSI reaction centers and transport electrons, generating a photocurrent. Despite attempts to catalyze dye reduction by NADPH, dye reduction occurred even without enzymes, with direct light-dependent reduction of NADPH and subsequent reduction of resazurin.

Summary: Three aromatic diimine ligands and their corresponding homoleptic copper(I) and copper(II) complexes were synthesized and characterized in this study. The nature of the ligand significantly influenced the photophysical and electrochemical properties of the complexes, and the coordination geometry of the complexes was affected by substituting pendant methyl groups with methoxy. The ligand was found to play a crucial role in the performance of the devices, with methoxy-substituted derivatives exhibiting unexpectedly high open circuit voltage after severe ligand exchange with tert-butylpyridine.

Summary: The idea of replacing coal with hydrogen dates back to 1874, and sustainable hydrogen production has always been a challenge. Utilizing photosynthesis to split water and store solar energy as hydrogen is an elegant approach. Cyanobacteria and green algae, unicellular photosynthetic organisms that possess hydrogenases, have inspired artificial and semi-artificial in vitro techniques for hydrogen production. These in vitro methods have also served as models for fusing cyanobacterial and algal hydrogenases with photosynthetic photosystem I (PSI) in vivo, which has recently been successfully demonstrated.

Summary: Respiratory complex I plays a crucial role in the electron transport chains of mitochondria and bacteria by efficiently coupling the redox reaction and proton pumping through a unique tunnel, leading to the synthesis of ATP. The separation of redox reaction and proton pumping in space and time raises the question of how these two reactions are so efficiently coupled. Recent structural data and molecular simulations provide insights into how quinone reduction and dynamics may be linked to proton pumping in complex I.

Summary: Photosystem I is a light-driven electron transfer device consisting of three iron-sulfur clusters F-X, F-A, and F-B. Experimental and computational studies have shown that F-X has a lower oxidation potential compared to F-A and F-B, which can be attributed to strong pairwise electrostatic interactions with surrounding residues.

Summary: The cyanobacterial bidirectional [NiFe]-hydrogenase is a pentameric enzyme that interacts with NAD(P)(+) and ferredoxin. It utilizes excited electrons from PSI for photohydrogen production and catalyzes the reverse reaction by feeding electrons into the photosynthetic electron transport. This enzyme might interact with photosynthetic complex I (NDH-1) and play a role in electron transfer.

Summary: The study focuses on improving the performance of dye-sensitized photoelectrochemical cell (DS-PEC) devices by tailoring the four-photon water oxidation half-reaction and using a Ru-based water oxidation catalyst (WOC) covalently bound to NDI dye functionalities to create a two-channel model. This model enables two separate parallel electron-transfer channels in the catalytic cycle, leading to the development of novel high-efficiency supramolecular complexes for DS-PEC devices. The proposed photocatalytic cycle of the two-channel model provides insight for building and conserving spin multiplicity as a design principle along the reaction coordinate.

Summary: Electron bifurcation is an energy-conserving process widely utilized in biochemistry, which generates high-energy products from substrates with lower reducing potential. The energetic challenge of the first bifurcation event, with a thermodynamically uphill step, is resolved by elucidating the unusually low two-electron potential of the bifurcating flavin.

Summary: Redox cofactors play a crucial role in mediating electron transfer in biological enzymes. One example is the [FeFe]-hydrogenase I from Clostridium acetobutylicum, which utilizes a terminal, non-canonical, His-coordinated, [4Fe-4S] cluster to mediate interfacial electron transfer. Substituting His for Cys in this enzyme results in changes in electron transfer properties and reactivity, demonstrating the importance of His coordination in controlling electron exchange.
