Figure 4
Geometry and comparison of the molecular packing of the TeCyt c6 structures with PDB codes 6tsy and 6tr1. Symmetry axes are indicated in blue. In space group C2 six molecules per asymmetric unit were identified in a `ring-like' assembly with a central threefold symmetry axis (upper panel). In space group H3 the asymmetric unit consists of three molecules, which are arranged like `twisted chains' in the crystal (lower panel). |
