Splicing of precursor messenger RNA (pre-mRNA) in yeast is executed by the spliceosome, which consists of five small nuclear ribonucleoproteins (snRNPs), NTC (nineteen complex), NTC-related proteins (NTR), and a number of associated enzymes and cofactors. Here, we report the three-dimensional structure of a Schizosaccharomyces pombe spliceosome at 3.6-angstrom resolution, revealed by means of s...
Photoisomerization of the retinal of bacteriorhodopsin initiates a cyclic reaction in which a proton is translocated across the membrane. Studies of this protein promise a better understanding of how ion pumps function. Together with a large amount of spectroscopic and mutational data, the atomic structure of bacteriorhodopsin, determined in the last decade at increasing resolutions, has sugges...
Various plannings in agriculture, hydrology, architecture and energy largely depend on the correct estimation of the amount of solar radiation. To estimate the solar radiation, most of the previous studies have used Angstrom model, having the values of sunshine hours as it's input, or regression equations through considering the climatic factors and elements affecting the radiation. In this stu...
A sub-angstrom probe size has been achieved with a Cs corrector [1, 2] for a scanning transmission electron microscope (STEM). In general, in the alignment of the Cs corrector, a user needs to select the aberration that needs to be corrected on the basis of aberration measurements. Once wrong selection of aberrations to be corrected is executed, the number of measurements and corrections is inc...
