... conserved CXXXC motif. A possible explanation of this result is that the soaking solution contained Cu(II) rather than Cu(I) ions, and the Cu(II) ions could then have catalysed oxidation of the conserved ... [17]. The thiol-disulfide oxidoreductase function of the CXXXC motif of human Sco proteins could therefore be impli- cated not only in the maturation of the Cu A si...
