Photosystem II, the pigment-protein complex responsible for water oxidation in photosynthesis, was found to exist in two different core conformations with altered antennae connectivity.
A large-scale phylogenetic inference of the ribonucleotide reductase family reveals a new distinct clade with implications on how nature adapted to environmental changes.
Guanosine tetraphosphate (ppGpp) is a pivotal regulator of chloroplast activity that is required for acclimation to nitrogen limitation in the model plant Arabidopsis.
Synechocystis switches its redox pools under reducing photomixotrophic conditions from utilizing NAD(H)- to ferredoxin-dependent enzymes and thereby balances its metabolism in a trade-off between energy conservation and chemical driving forces.
Biochemical analysis on hetero-mutated c10 subunits ring and molecular dynamics simulations demonstrate the cooperation among c-subunits of FoF1-ATP synthase in rotation-coupled proton translocation.
The small ubiquitin-like modifier system directly regulates components of the chloroplast protein import apparatus, that is, TOC proteins, to control chloroplast biogenesis and plant development.
The nature of the phycobilisome–photosystem II supercomplex on the native thylakoid determined with cryo-electron tomography at an unprecedented resolution reveals that one phycobilisome interconnects with six photosystem monomers.
The necessity of studying extremophile organisms is exemplified by the structure of photosystem I from a high-light tolerant cyanobacteria, demonstrating the relationship between the structure and function in photosystem I.
