direction of the Au(111) surface and weakly interact with the substrate and with neighboring chains (see Supp. Fig.3). High-resolution images obtained at high tunneling currents (see Fig.1c) show an intramolecular wiggling pattern with a periodicity of 2.5 ± 0.1 Å (see Fig.1e)...
Systemic AA amyloidosis is a world-wide occurring protein misfolding disease of humans and animals. It arises from the formation of amyloid fibrils from serum amyloid A (SAA) protein. Using cryo electron microscopy we here show that amyloid fibrils which
Positively charged arginine side chains also likely play a role in charge stabilization. Finally, WAXD results finds that the silk is at least 7-8% crystalline, with beta-sheet interplane spacings of 3.7 and 4.5 A. 展开 关键词: SPIDER DRAGLINE SILK BOMBYX-MORI MAGIC-ANGLE SECONDARY STRUCTURE ...
Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms.
and piperazinyethoxyethyl side chains, is known to stabilize a telomeric G-quadruplex49. Thus, in spite of displaying certain structural differences, synthetic G-quartets have been used as stable substitutes for canonical G-quadruplex. Hence, the observed Fmoc-G-PNA tetramer may be considered as ...
Taking advantage of the strong hydrophobicity of the anticancer drug camptothecin (CPT), the CPT molecule was conjugated to a class of low-molecular-weight (MW) poly(ethylene glycol) (PEG) chains (MW = 500, 1000, and 2000), forming an amphiphilic prodrug. The CPT-PEG prodrug formed stable...

The invention provides methods for forming hydrogels having desired physical or chemical properties. As described above, useful functional groups can be inserted into the hydrogel by virtue of the chemistry of bridging molecules, such as the side chains of amino acids. Moreover, the desired physical...
