Structure Determination Best Online Journals
Structure determination is a procedure by which the three-dimensional atomic coordinates of a molecule or biomolecule are solved using an analytical technique. Many techniques are used in structure determination, most commonly X-ray crystallography, NMR spectroscopy, electron microscopy and molecular modelling. Structure determination of G protein-coupled receptors (GPCRs) in the inactive state bound to high- affinity antagonists has been very successful through the implementation of a number of protein engineering and crystallization strategies. However, the
structure determination of GPCRs in their fully active state coupled to a G protein remains very challenging. mini-G proteins were developed, it recapitulate the coupling of a full heterotrimeric G protein to a GPCR despite being but one-third of the dimensions . most
structure determination techniques involve the diffraction of electromagnetic or matter waves of wavelengths comparable to atomic dimensions, Owing to the highly ordered arrangement of
atoms as scattering centres during a space lattice. This variation arises from constructive and destructive interference of scattered beams from the planes related to the various
atoms present within the lattice. The result's seen by an imaging detector as a pattern of diffraction spots or rings.
