Green to the core Light from Sun powers most life on today's Earth in some way. The of photosynthetic apparatus where charge separation occurs, reaction center (RC), is thought have originated a single time and diverged, yielding new kinds complexes adapted different tasks environments. Chen et al. now present an important missing puzzle piece our understanding evolution RCs: cryo–electron microscopy structure homodimeric type I RC green sulfur bacterium bound light-harvesting protein....
Acaryochloris marina is a unique cyanobacterium using chlorophyll d (Chl ) as its major pigment and thus can use far-red light for photosynthesis. Photosystem II (PSII) of A. associates with number prochlorophyte Chl-binding (Pcb) proteins to act the light-harvesting system. We report here cryo-electron microscopic structure PSII-Pcb megacomplex from at 3.6-angstrom overall resolution 3.3-angstrom local resolution. The organized tetramer consisting two PSII core dimers flanked by sixteen...
Photosystem I (PSI) is a large protein supercomplex that catalyzes the light-dependent oxidation of plastocyanin (or cytochrome c6 ) and reduction ferredoxin. This catalytic reaction realized by transmembrane electron transfer chain consisting primary donor (a special chlorophyll (Chl) pair) acceptors A0 , A1 three Fe4 S4 clusters, FX FA FB . Here we report PSI structure from Chl d-dominated cyanobacterium Acaryochloris marina at 3.3 Å resolution obtained single-particle cryo-electron...
Ribulose 1,5-bisphosphate carboxylase/oxygenase (RuBisCO) catalyzes the initial carbon fixation reaction in Calvin-Benson-Bassham cycle plants and most microbial autotrophs. Among many forms of RuBisCOs, form-I, a protein complex containing 8 large small subunits, is common, representing over 90% all known RuBisCOs. Although form-I RuBisCO structures have been determined, no structure has reported for form-IAq RuBisCO. Here, at ultrahigh (1.55 angstrom) resolution, we detail heat-stable from...
The reaction center-light harvesting 1 (RC-LH1) complex converts solar energy into electrical energy, driving the initiation of photosynthesis. authors present a cryo-electron microscopy structure RC-LH1 isolated from marine photoheterotrophic bacterium Dinoroseobacter shibae. RC comprises four subunits, including three-heme cytochrome (Cyt) c protein, and is surrounded by closed LH ring composed 17 pairs antenna subunits. Notably, novel subunit with an N-terminal "helix-turn-helix" motif...
Anoxygenic phototrophic sulfur bacteria flourish in contemporary and ancient euxinic environments, driving the biogeochemical cycles of carbon sulfur. However, it is unclear how these strict anaerobes meet their high demand for iron iron-depleted environments. Here, we report that pyrite, a widespread highly stable sulfide mineral anoxic, low-temperature can support growth metabolic activity anoxygenic by serving as sole source under conditions. Transcriptomic proteomic analyses revealed...
The process of oxygenic photosynthesis is primarily driven by two multiprotein complexes known as photosystem II (PSII) and I (PSI). PSII facilitates the light–induced reactions water–splitting plastoquinone reduction, while PSI functions light–driven plastocyanin-ferredoxin oxidoreductase. In contrast to highly conserved structure among all oxygen–evolving photosynthetic organisms, structures exhibit remarkable variations, especially for organisms that grow in special environments. this...
In view of the uneven artificial sowing, low as well fact that existing seeders cannot meet sowing requirements Pteris vittata, this paper designed an automatic plug seeder by using method spraying and after mixing spores water. order to obtain optimum working parameters seeder, response surface (RSM) was employed design experiments evaluate results with purpose optimizing for improving uniformity. The such distance between nozzle angle transmission speed were selected, then regression...
Sweetpotato (Ipomoea batatas L.) has great potential for combating micronutrient malnutrition and vitamin A deficiency. To explore the of combining different micronutrients in same cultivar through genetic improvement, we assessed variation Fe Zn contents among 21 genotypes 5 growing locations eastern region China. Large genotype-dependent differences were found storage roots. The content ranged from 2.68 to 4.64 mg/100 g dry weight basis (dwb), whereas 2.92 6.95 dwb. caused by genotypes,...
