Figure 3. Stereo Representation of the Overall Structure of
DgW-FDH from D. gigasThe small domain (214 amino acid residues)
is represented in purple, and the large domain (977 amino acid
residues) is colored after its domain classification. Domain I
(red) corresponds to residues 9-68, 575-603, and 647-734; domain
II (green) contains residues 69-157, 410-574, and 604-646;
domain III (yellow) is defined by residues 157-409; domain IV
(blue) is defined by residues 735-977. Domain IV can be divided
into two subdomains, IVa (residues 735-795) and IVb (residues
796-977). The insertions (relative to the homologous NAP and
FDH-H structures) present in several domains are shown in
gray.(B) Representation of the four "exploded" domains of the
large 977 aa subunit.(C) Comparison of the domain organization
of DgW-FDH, D. desulfuricans NAP, and E. coli FDH-H. The
insertions in DgW-FDH are depicted as dashed areas.(D) Stereo Ca
trace numbered every 20 residues for domains II and III
(top).(E) Stereo Ca trace numbered every 20 residues for domains
I and IV and for the small subunit (below).
