Solution scattering studies of dimeric and tetrameric spectrin. 1982

M H Reich, and Z Kam, and H Eisenberg, and D Worcester, and E Ungewickell, and W B Gratzer

The structure of spectrin dimers and tetramers in solution has been examined by light, low-angle X-ray and neutron scattering. The results show a good correspondence between the solution dimensions of these molecules and their appearance in the electron microscope after shadowing. The scattering profiles are not compatible with an extended rod-like character, but reflect the presence of a considerable degree of bending. The radii of gyration of the dimer and tetramer were determined to be 170 and 375 A and the cross-section radii of gyration 14 and 12.3 A, respectively. Both are thus long, thin, rather bent molecules, and the tetramer is twice the length of the dimer.

D009502 Neutrons Electrically neutral elementary particles found in all atomic nuclei except light hydrogen; the mass is equal to that of the proton and electron combined and they are unstable when isolated from the nucleus, undergoing beta decay. Slow, thermal, epithermal, and fast neutrons refer to the energy levels with which the neutrons are ejected from heavier nuclei during their decay. Neutron
D011487 Protein Conformation The characteristic 3-dimensional shape of a protein, including the secondary, supersecondary (motifs), tertiary (domains) and quaternary structure of the peptide chain. PROTEIN STRUCTURE, QUATERNARY describes the conformation assumed by multimeric proteins (aggregates of more than one polypeptide chain). Conformation, Protein,Conformations, Protein,Protein Conformations

D012542 Scattering, Radiation The diversion of RADIATION (thermal, electromagnetic, or nuclear) from its original path as a result of interactions or collisions with atoms, molecules, or larger particles in the atmosphere or other media. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed) Radiation Scattering,Radiation Scatterings,Scatterings, Radiation
D013049 Spectrin A high molecular weight (220-250 kDa) water-soluble protein which can be extracted from erythrocyte ghosts in low ionic strength buffers. The protein contains no lipids or carbohydrates, is the predominant species of peripheral erythrocyte membrane proteins, and exists as a fibrous coating on the inner, cytoplasmic surface of the membrane. alpha-Spectrin,beta-Spectrin,alpha Spectrin,beta Spectrin
D014961 X-Ray Diffraction The scattering of x-rays by matter, especially crystals, with accompanying variation in intensity due to interference effects. Analysis of the crystal structure of materials is performed by passing x-rays through them and registering the diffraction image of the rays (CRYSTALLOGRAPHY, X-RAY).

D046911 Macromolecular Substances Compounds and molecular complexes that consist of very large numbers of atoms and are generally over 500 kDa in size. In biological systems macromolecular substances usually can be visualized using ELECTRON MICROSCOPY and are distinguished from ORGANELLES by the lack of a membrane structure.
