HUMAN RANTES, NMR, 13 STRUCTURES
Contents |
Overview
The solution structure of the chemokine RANTES (regulated on activation, normal T-cell expressed and secreted) has been determined using NMR, spectroscopy. Backbone and side-chain 1H and 15N assignments have been, obtained using a combination of two-dimensional homonuclear and, three-dimensional heteronuclear spectra. Regular elements of secondary, structure have been identified on the basis of a qualitative, interpretation of NOE data, J(NH-H alpha) coupling constants, and amide, exchange rates. Three-dimensional structures were calculated from a total, of 2146 experimental restraints using a combination of distance geometry, and simulated annealing protocols. For the 13 best structures the average, backbone (N, C alpha, C) atomic rmsd from the mean coordinates for, residues 5-65 is 0.64 A (+/- 0.14 A) for the dimer and 0.50 A (+/- 0.08 A), for the individual monomers. Each monomer consists of a three-stranded, antiparallel beta-sheet (residues 26-30, 38-43, 48-51) in a Greek key, motif with a C-terminal helix (56-65) packed across the sheet, an, arrangement similar to the monomeric structure of other members of this, chemokine family (IL-8, PF4, MGSA/Gro alpha, and MIP-1 beta). Overall, the, RANTES dimer resembles that previously reported for MIP-1 beta.
