Ultra-high resolution structure of Pyrococcus abyssi rubredoxin W4L/R5S
OverviewOverview
The crystal structure of Pyrococcus abyssi rubredoxin mutant W4L/R5S was, solved by direct methods. The model of the air-oxidized protein was, refined by partially restrained full-matrix least-squares refinement, against intensity data to 0.69 A resolution. This first, ultrahigh-resolution structure of a rubredoxin provides very detailed and, precise information about the Fe(SCys)(4) centre and its environment, the, peptide-backbone stereochemistry, H atoms and hydrogen bonds, static and, dynamic disorder, the solvent structure and the electron-density, distribution. P. abyssi rubredoxin W4L/R5S is the first of a series of, mutants studied by atomic and ultrahigh-resolution X-ray crystallography, which are expected to contribute to the understanding of, structure-function relationships in iron-sulfur proteins.
