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.
A potentially useful cyanobacterial sulfated exopolysaccharide and its biosynthesis and regulation genes, which contribute to the laboratorial bloom formation, are elucidated for the first time among prokaryotes.
An iron-sensitive gene cluster encodes proteins that co-localize with phytotransferrin endosomes and are involved in key intracellular iron transformation and trafficking processes in a model marine diatom.
Light-harvesting complex stress-related is a protein from photosynthetic green algae that prevents damage from sunlight via two distinct conformational processes, which protect against different timescales of solar fluctuations.
A novel B12 containing photoreceptor is synthesized as two different isoforms that interact with the same transcription factor, with one isoform directing activation and the other promoting repression of photosystem synthesis.
The structures of photosystem II, with the water-oxidizing Mn4CaO5-cluster fully removed and in an intermediate assembly state, show that photoassembly is facilitated by perfectly pre-arranged protein ligands of the five metal ions.
