The structure of the all-cysteinyl-coordinated D14C variant of [4Fe–4S] ferredoxin from the hyperthermophilic archaeon Pyrococcus furiosus has been determined to 1.7 Å resolution from a crystal belonging to space group C2221 with two types of molecules, A and B, in the asymmetric unit. A and B molecules have different crystal packing and intramolecular(More)
Heterometallic [AgFe3S4] iron–sulfur clusters assembled in wild-type Pyrococcus furiosus ferredoxin and two variants, D14C and D14H, are characterized. The crystal structure of the [AgFe3S4] D14C variant shows that the silver(I) ion is indeed part of the cluster and is coordinated to the thiolate group of residue 14. Cyclic voltammetry shows one redox pair(More)
