Introduction In comparison to the vibrant colors of the flower, the ‘leaf’ has nothing special to offer as most are green-colored attributed to the presence of chlorophyll. But their attractiveness lies in their varying shapes and sizes; from the uncommon butterfly-shaped leaf ofChristia obcord...
Second, biotinylated molecule can bind to endogenous biotin-binding proteins such as eggs or bacteria [19]. To overcome these limitations, an avidin analogue, streptavidin, derived from Streptomyces avidinii, has been exploited as a pretargeting platform. The streptavidin/biotin system has an ...
We adopt widely-used metrics26,38to evaluate the quality of molecules generated by PMDM: (1)Vina Scoreestimates the binding affinity between the ligand and the target pocket which is the most important measurement to evaluate how the generated molecule fits into the protein pocket of interest; (...
Vesicular stomatitis virus (VSV) is a negative-strand RNA virus with a non-segmented genome, closely related to rabies virus. Both have characteristic bullet-like shapes. We report the structure of intact, infectious VSV particles determined by cryogenic
Different molecules have different shapes. The shape of a molecule is dictated by the arrangement of Electron Pairs. This is because Electron Pairs repel each other. The molecule settles in a state where the Electron Pairs are furthest apart from each other. Different types of Electron Pairs ...
Small molecule therapeutics Drug discovery Medicinal chemistry New modalities Artificial intelligence Societal impact Introduction The year 2021 marks the 125th anniversary of the Bayer Chemical Research Laboratory in Wuppertal, Germany (Fig. 1).1., 2. This research facility has been vital for Bayer’s...
After synthesis, polypeptide chains are folded or pleated into different shapes, called their Secondary Structure. Two common examples of secondary structures are Alpha Helices and Beta Pleated Sheets. Secondary structure is held together by many Hydrogen bonds, overall giving the shape great stability....

One critical feature of the obtained NbSe2species is that they have radially deformed nanotubes with elliptical shapes (Fig.1a, b), where Se-Nb-Se sandwiched repeating units are assembled clockwise to form a flat tube, distinguishing this study from all reported coaxial tubes20,25. Based on th...
