Figure 2
Overall structure of BoSDR. (a) Like other SDRs, the protomer of BoSDR has a central β-sheet flanked by α-helices. The NAD+ coenzyme is shown in ball-and-stick representation with purple C atoms. Other heteroatoms are shown using standard coloring. Here, β-sheets are shown in green, α-helices are shown in blue and loops are in yellow. (b) The overall structure of BoSDR is tetrameric. Chain A is colored red, chain B is orange, chain C is colored by secondary structure as in (a) and chain D is yellow. The NAD+ is shown in ball-and-stick representation with the coloring as in (a). |
