![]() Frequently, the exchange hinges contain proline-rich motifs which are often in high strain conformations. It is also possible that strand-swapping occurs during folding of nascent polypeptide chains. However, there is often a high energy barrier for the conversion as it often goes through an unfolded state. In domain swapped proteins, the same structural elements are involved in the final 3D structure, and so there is little overall energetic difference between the monomer and the swapped oligomers. 3D domain swapping has been proposed to be a mechanism of protein oligomerization, aggregation, evolution of oligomeric proteins from single domains and amyloidogenesis. A method for enantiomeric excess (ee) determination of THFA is presented using a recently proposed chiral self-tag = -strand swapping, which is a subset of 3D domain swapping, has been found to mediate cell-cell adhesion by cadherins. The study further reveals an interesting chirality dependent structure-energy ordering relationship. To identify the conformers responsible for the extremely dense rotational spectra observed, it was essential not only to locate several hundred homo/heterochiral (THFA) 2 minima in ab initio calculations but also to evaluate the energetic connectivities among the minima. Two drastically different scenarios are possible for the detectable (THFA) 2: a kinetically preferred dimer bound by feeble interactions between two trans-THFAs or a thermodynamically favored dimer with a double hydrogen-bonded ring structure between two cis subunits. THFA shows a strong preference for the trans- over the cis-COOH configuration. ![]() In Your rainbow panorama, it becomes clear that colour perception is relative, seeing is embodied.Chirality recognition in dimers of tetrahydro-2-furoic acid (THFA) was studied in a conformer-specific manner using rotational spectroscopy and theoretical approaches. Stronger hues in their peripheral vision, where the glass curves away, coax them to keep moving.Only through movement are visitors able to perceive the full range of colours. ![]() When they stand still, the world outside appears almost monochromatic but with heightened details.The longer they stand in one place, the more their vision adjusts to the colour of the pane before them, making the tint grow pale. Moving around the work, visitors have the sense of being within an endless loop, transitioning smoothly from one colour to the next through the entire spectrum, while their perception of the city scape constantly changes. Installed in 2011, Your rainbow panorama offers visitors sweeping views of the city, the sky, and the distant horizon. In 2007 Eliasson and his studio won an invited architectural competition with their proposal to transform the rooftop of the museum, which was built by schmidt hammer lassen architects. One hundred fifty metres around and glazed with rainbow-coloured glass, the work divides Aarhus into various colour zones and acts as a beacon for people moving about the city – an effect that is heightened at night when lights running the circumference of the walkway illuminate it from within. Situated a top ARoS Aarhus Art Museum, in Denmark, the elevated 360-degree walkway Your rainbow panorama is recognisable from a far. ![]()
