Open AccessEnantioselectivity of discretized helical supramolecule consisting of achiral cobalt phthalocyanines via chiral-induced spin selectivity effect
Enantioselectivity of helical aggregation is conventionally directed either by its homochiral ingredients or by introduction of chiral catalysis. The fundamental question, then, is whether helical aggregation ...

Open AccessMeasurement of charges and chemical bonding in a cryo-EM structure
Hydrogen bonding, bond polarity, and charges in protein molecules play critical roles in the stabilization of protein structures, as well as affecting their functions such as enzymatic catalysis, electron tran...

Open AccessStructural resolution of a small organic molecule by serial X-ray free-electron laser and electron crystallography
Structure analysis of small crystals is important in areas ranging from synthetic organic chemistry to pharmaceutical and material sciences, as many compounds do not yield large crystals. Here we present the d...

Open AccessStructure of a monomeric photosystem I core associated with iron-stress-induced-A proteins from Anabaena sp. PCC 7120
Iron-stress-induced-A proteins (IsiAs) are expressed in cyanobacteria under iron-deficient conditions. The cyanobacterium Anabaena sp. PCC 7120 has four isiA genes; however, their binding property and functional ...

Open AccessCore and rod structures of a thermophilic cyanobacterial light-harvesting phycobilisome
Cyanobacteria, glaucophytes, and rhodophytes utilize giant, light-harvesting phycobilisomes (PBSs) for capturing solar energy and conveying it to photosynthetic reaction centers. PBSs are compositionally and s...

Open AccessMachine learning-based real-time object locator/evaluator for cryo-EM data collection
In cryo-electron microscopy (cryo-EM) data collection, locating a target object is error-prone. Here, we present a machine learning-based approach with a real-time object locator named yoneoLocr using YOLO, a ...

Open AccessStructure of the far-red light utilizing photosystem I of Acaryochloris marina
Acaryochloris marina is one of the cyanobacterial species that can use far-red light to drive photochemical reactions for oxygenic photosynthesis. Here, we report the structure of A. marina photosystem I (PSI) re...

Open AccessHigh-resolution cryo-EM structure of photosystem II reveals damage from high-dose electron beams
Photosystem II (PSII) plays a key role in water-splitting and oxygen evolution. X-ray crystallography has revealed its atomic structure and some intermediate structures. However, these structures are in the cr...

Open AccessApple latent spherical virus structure with stable capsid frame supports quasi-stable protrusions expediting genome release
Picorna-like plant viruses are non-enveloped RNA spherical viruses of ~30 nm. Part of the survival of these viruses depends on their capsid being stable enough to harbour the viral genome and yet malleable eno...
