==NMR-validated structural model for oxidized R.palustris cytochrome c556==
-
The structure of oxidized Rhodopseudomonas palustris cytochrome c(556) has, been modeled after that of high-spin cytochrome c' from the same, bacterium, the latter being the protein with the greatest sequence, identity (35%) among all sequenced proteins in the genomes. The two, proteins differ in the number of ligands to iron and in spin state, the, former being six-coordinate low-spin and the latter five-coordinate, high-spin. In order to validate this modeled structure, several structural, restraints were obtained by performing a restricted set of NMR, experiments, without performing a complete assignment of the protein, signals. The aim was to exploit the special restraints arising from the, paramagnetism of the metal ion. A total of 43 residual-dipolar-coupling, and 74 pseudocontact-shift restraints, which together sampled all regions, of the protein, were used in conjunction with over 40 routinely obtained, NOE distance restraints. A calculation procedure was undertaken combining, the program MODELLER and the solution structure determination program, PARAMAGNETIC DYANA, which includes paramagnetism-based restraints. The, directions and magnitude of the magnetic susceptibility anisotropy tensor, were also calculated. The approach readily provides useful results, especially for paramagnetic metalloproteins of moderate to large, dimensions.
