X-ray structure of the gamma-subunit of a dissimilatory sulfite reductase: fixed and flexible C-terminal arms.

Abstract

The X-ray structure of the gamma-subunit of the dissimilatory sulfite reductase (DsrC) from Archaeoglobus fulgidus was determined at 1.12 and 2.1A resolution, in the two crystal forms named DsrC(nat) and DsrC(ox) the latter being cocrystallized with the oxidizing agent tert-butyl hydroperoxide. The fold corresponds to that of the homologous protein from… (More)
