Models are refined against the experimental PDF data by reverse Monte Carlo simulations and analysed in terms of prime structural characteristics such as metal-to-metal bond lengths, bond angles and first coordination numbers for Pt and Ru atoms. Analysis indicates that, though of a similar type,...
The structural similarity of Omp32 is greatest to OmpF (PDB code 2OMF) as judged by the superimposition of Cα atoms. A total of 214 Cα positions, which contain almost all of the 207 β-strand amino acids, were structurally aligned in the fit and gave an average root mean square (rms...

The presence of a water layer, adjacent to the surface, induces large disorder in the Ca positions such that these atoms exhibit finite populations up to 1 Å above their normal lattice positions, see Fig. 3. To examine this further, we performed a simulation with a single Ca atom ...
This might be attributed to the occurring rearrangement of the structure for the atoms, resulting in a deformation of the composite structure. The nominal crystallite size of the structure is calculated based on the Scherrer equation as previously r eported57. k D crystallite size = βCosθ...
3~1. · In this space group the sodium atoms are in two independent 3-fold sets, and each fluorine octahedron is free to rotate about its 3-fold axis. Continued refinement of the structure with this greater freedom reduced~ to 0.28, and the thermal parameter-of one sodium atom became ...
Two hydrogen bonds were found for N566 of ECE-1 with the P2’ amide nitrogen and oxygen atoms of the terminal carboxylate while its equivalent N571 of XCE maintained only one H-bond with the P2’ amide nitrogen. In XCE, however, V565 of ECE-1 was replaced with L570 amino acid, but...
It was found that low-coordinated Pt atoms can be formed during electrochemical activation [18] or acid treatment [19], and then serve as the active sites. The followed decrease in current (Fig. 2d) may attribute to the aggregation and recombination of the low-coordinated Pt atoms on the ...
The proteins were superimposed on the Cα atoms of these residues. The cryptochrome protein backbone is shown in blue tubes. The thymine dimer model is taken from Medvedev and Stuchebrukhov (2001) with kind permission of the authors. (B) Cryptochrome DASH-specific amino acids (Phe148, Leu153...
