Abstract:
Thioredoxins play key roles in the cellular response to oxidative stress. Three isoforms of thioredoxin have been identified in Saccharomyces cerevisiae: two that are cytosolic (Trx1 and Trx2) and one that is mitochondrial (Trx3). In the present work, the cytosolic form Trx1 was cloned, expressed, purified and crystallized. Crystals were obtained by the hanging-drop vapour-diffusion method. A data set was collected from a single crystal to 1.7 A resolution. The crystal belongs to space group P2(1)2(1)2(1), with unit-cell parameters a = 32.29, b = 46.59, c = 64.20 A, alpha = beta = gamma = 90 degrees .

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal...

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
Crystal Growth: Principles of Crystallization
Initiating crystallization involves manipulating the concentration of the solute and the temperature of the solution. Since crystal growth occurs when the ratio of concentration and solubility of the solute in the solvent...
Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
