| Popis | The flavin adenine dinucleotide-dependent enzyme FerB from Paracoccus denitrificans reduces a range of sub strates, including chromate, ferric complexes, benzoquinones and naphtoquinones. The reduced form of nicotinamide adenine dinucleotide serves as a source of electrons. Recombinant unmodified and selenometionine-substituted (Se-Met) FerB derivatives were crystallized, diffraction data for both forms were collected and the phase problem for Se-Met FerB dimer was solved by three-wavelength multiple anomalous dispersion, followed by the combination of molecular replacement and single-wavelength anomalous diffraction phasing. A molecular replacement solution of unmodified FerB tetramer was obtained using Se-Met structure as a search model. |
