Crystal structure of oxygen-evolving photosystem II from Thermosynechococcus vulcanus at 3.7-Å resolution.Photosystem II (PSII) is a multisubunit membrane protein complex performing light-induced electron transfer and water-splitting reactions, leading to the formation of molecular oxygen. The first ...

The molecular structure at the buried interface between 2D crystals of C8-DNBDT-NW and the substrate was characterized by assessing the electron density profile along the depth direction, determined by sensitive XRR measurements (see the “Methods” section and Supplementary Figs. 1–3 in Supplementa...
Although the crystal structure of the monomeric cyanide derivative has previously been determined, the manner by which oligomerization acts to lower the oxygen affinity and confer a strong Bohr effect has, until now, been speculative. Results: We have determined the crystal structure of deoxygenated ...
Examination of the structure also reveals noncovalent interactions between the adduct and two residues in the active site. The epsilon and eta nitrogens of the guanidinium side chain of Arg-39" from a neighboring dimer interact respectively with the C-2 carbonyl oxygen and one C-1 carboxylate ...
11.5 Crystal Structure A crystal is a material that has a periodic array of molecules or ions. When the periodic array extends throughout the entire crystal it is called a single crystal. Some materials are made of tightly bound small crystals and are referred to as polycrystalline materials. ...
Structure Crystals can be grown under moderate conditions from all 92 naturally occurringelementsexcept helium, and helium can be crystallized at low temperatures by using 25 atmospheres of pressure.Binarycrystals are composed of two elements. There are thousands of binary crystals; some examples are ...
a holo structure with bound ThDP and a structure containing the enamine reaction intermediate (Fig.1). We also dockedMtDXPS inhibitors found in the literature and provide a structural rationale for their inhibitory activity. In addition to providing a molecular model of this important anti-infective...
Crystals of un-phosphorylated protein were obtained and diffraction data collected to 2.5 Å resolution. The structure of NM-IIANtr was solved by molecular replacement using the coordinates of the E. coli nitrogen regulatory protein IIAntr [PDB: 1A6J] as the starting model. The overall fold ...
The crystal structure of the oxygen-bridged dimer formed between copper(II) bromide and 4-methylpyridine-1-oxide has been determined and refined to a final R value of 0.027. The dinuclear units crystallize in the monoclinic space group P2 1/c with dimensions: a = 6.086(1), b = 15.064(3...
