We report the results on the structure of the binary dense CO2−water interface at 20 MPa and 318 and 338 K and 28 MPa and 318 K, as investigated by molecular dynamics computer simulations. Realistic potential models are used to describe the interactions, and the Ewald summation technique is...
b) and determined the structure of the complex using single-particle cryogenic electron microscopy. Three-dimensional reconstruction with four-fold averaging yielded a density map with 3.0 Å overall
The potential energy hypersurface of sucrose has been examined by molecular mechanics calculations (MM3(92)) interfaced with two different algorithms for conformational searching. The first uses the systematic grid-search approach. The second algorithm, which has a lower CPU requirement, is the so-ca...
The structure shows 26-fold rotational symmetry and intricate intersubunit interactions of each subunit with up to six partners, which explains the structural stability. The inner surface is charged both positively and negatively. Positive charges on the P ring (the part of the LP ring that is ...
Using lipidic cubic phase crystallization and microfocus X-ray diffraction, we determined the structure of human GLUT3 in complex with D-glucose at 1.5 resolution in an outward-occluded conformation. The high-resolution structure allows discrimination of both α- and β-anomers of D-glucose. Two ...
The recombinant enzyme catalyzed inulin synthesis from sucrose like the wild-type enzyme. Inulosucrase presents an unusual structure: its N-terminal region is similar to the variable region of glucosyltransferases, its catalytic domain is similar to fructosyltransferases from various microorganisms, and...
Cryo-EM structure of CVA16 in complex with 9B5 Fab To further investigate the structural basis of CVA16 neutralization by 9B5 MAb, we performed cryo-EM study on the CVA16–9B5 Fab complex. SDS-PAGE analysis of the purified CVA16 sample revealed the presence of VP0, VP1, VP2 and, VP...
. In the structure of BRIL-SLC19A1, the last helix of BRIL rotated around its joint region with the TM1 of SLC19A1, and as a result, the four-helical bundle of BRIL resided parallel to the cell membrane. In addition, BRIL leaned on the intracellular loop between TM4 and TM5 of ...
