Figure 3.

NDH-2 conserved region around the CxxC motif. (A) MSA displayed as LOGO representation of a 78 PNDR class IV subset with putative Cu(II)-reductase activity. (B) Derived motifs signature written in PROSITE pattern form. The shadowed blocks represent conserved regions with putative functional assignment. Grey, cyan, yellow and magenta colors correspond to: the second FAD, Cu(I), Cu(II) and quinone binding motifs, respectively.
