Figure 2.
Fig. 2. Structural comparison. (A) Ribbon diagram of the D.
vulgaris FMN-bp (Accession No. 1AXJ) with bound FMN (magenta)
showing a single conformer (model 1) out of 20 and oriented and
colored as the left subunit in Fig. 1A. (B) Ribbon diagram of
the S. cerevisiae PNPOx dimer (Accession No. 1CI0) with bound
FMN (magenta) with the central β-sheet of the left subunit
oriented and colored as in Fig. 1A. The additional regions in
PNPOx compared to Rv1155 and FMN-bp are shown in red, while
those that significantly differ between Rv1155, FMN-bp and PNPOx
are indicated in orange. In the left subunit, the FMN-binding
site at the dimer interface is shown through a transparent
molecular surface.
