Figure 3
A stereoview of the superposition of (IA), (IB), (IIA) and (IIB). Molecular fitting was performed for the main chains using ProFit (Martin, 1996). The figure was drawn using RasMol (Bernstein, 2000) and POV-RAY3.5 (POV-Team, 1991). The r.m.s. deviations are 0.233–0.586 Å. From left to right at the base, the molecules are in the sequence (IIB), (IA), (IIA) and (IIB). |
