Figure 1
Ribbon diagram of the α trimer as seen along a molecular threefold axis (black triangle). The three monomers are shown in green, blue and red. Each monomer contains two similar modules related by a pseudo-dyad axis (arrow) perpendicular to the threefold axis. This figure was prepared using MOLSCRIPT (Kraulis, 1991) and Raster3D (Merritt & Murphy, 1994). |
