As shown in Supplementary Figs S12 and S13, most of residues in the tails had no secondary structure; however, bend and turn structures defined by DSSP were observed in the models, suggesting that the H2A and H2B tails are not completely random coils. The average dis- tabanenndcdeβis ...
CLDM exhibits the following positive characters: (1) availability in per os and intravenous administrations (switch therapy is possible), (2) good distributions to tissue and cells, (3) suppression19 of toxin production by Streptococcal strains and (4) expected reasonable production cost of LCM/CLD...
Lewis structure is known as the illustration of the molecule which shows the anionic and cationic parts of an atom. The atom which gains an electron is shown by a negative charge and the atom that loses an electron is shown by a positive charge....
The three-dimensional hydrogen-bonded network can be seen as a stacking of layers parallel to the (100) planes. Each layer is formed by chains of alternating positive and negative ions along the b and c axes. Hydrogen bonding of adjacent layers forms alternating chains along the a axis. A ...
Anastellin (AN), a fragment of the first type III module in fibronectin (FN), initiates formation of superfibronectin, a polymer which resembles the native cell-derived fibrillar FN found in the extracellular matrix of many tissues, but which displays remarkably different functional properties. Her...
摘要: The reaction of 'GaI' synthesized by ultrasonic irradiation of gallium and diiodine in the presence of phosphanes leads to new gallium subhalides in which gallium–gallium bonds are involved.DOI: 10.1039/A703776G 被引量: 51 年份: 1997 ...
