Figure 1
Ribbon diagram of the 2-Zn insulin hexamer viewed down the crystallographic threefold axis. Residues, which are coloured according to chain type (A chain in green, B chain in red), are represented by their Cα atoms only, except for residues HisB10 which coordinate to the zinc ions (grey sphere). This figure was produced using BobScript (Esnouf, 1997). |
