1.8.98.1 | Fe-S center |
subunit HdrB contains a Fe-S cluster fixed by cysteines of two cysteine-rich CCG domain sequence motifs, CX31-39CCX35-36CXXC. Electron paramagnetic resonance spectra are consistent with with the attachment of the substrate to the cluster in HdrABC and infer that the cluster's magnetic properties arise from the CCG binding motif |
