    The role of the local environment on the structural heterogeneity of carotenoid β-ionone rings

    Our analysis of the X-ray crystal structure of canthaxanthin (CAN) showed that its ketolated β-ionone rings can adopt two energetically equal, but structurally distinct puckers. Quantum chemistry calculations ...

    Molecular Self-Assembly as a Trigger of Life Origin and Development

    The origin and reason for the homochirality of living cells go with the problem of a relatively narrow spectrum of the actual biological monomers compared to the whole theoretically possible spectrum of amino ...

    Chirality Driven Twisting as a Driving Force of Primitive Folding in Binary Mixtures

    The N-trifluoroacetylated α-aminoalcohols (TFAAAs) are able to form quasi-one-dimensional supramolecular fibers (strings) when chirally pure, and isometric precipitates in the racemate. The strings’ formation lea...

    Spontaneous Resolution and Super-coiling in Xerogels of the Products of Photo-Induced Formose Reaction

    This work addresses the supramolecular self-organization in the xerogels of formose reaction products. The UV-induced formose reaction was held in over-saturated formaldehyde solutions at 70∘C without a catalyst....

    Coupled rows of PBS cores and PSII dimers in cyanobacteria: symmetry and structure

    Phycobilisome (PBS) is a giant water-soluble photosynthetic antenna transferring the energy of absorbed light mainly to the photosystem II (PSII) in cyanobacteria. Under the low light conditions, PBSs and PSII...

    Assembly of photoactive orange carotenoid protein from its domains unravels a carotenoid shuttle mechanism

    The photoswitchable orange carotenoid protein (OCP) is indispensable for cyanobacterial photoprotection by quenching phycobilisome fluorescence upon photoconversion from the orange OCPO to the red OCPR form. Cyan...

    Electronic coupling of the phycobilisome with the orange carotenoid protein and fluorescence quenching

    Using computational modeling and known 3D structure of proteins, we arrived at a rational spatial model of the orange carotenoid protein (OCP) and phycobilisome (PBS) interaction in the non-photochemical fluor...
