Figure 1. (a) A ribbon diagram of TcaXI (left) and TthXI subunits. Each subunit has two domains. a-Helices are in cyan, 310-helices in green, and b-strands in orange. Secondary structures have been assigned with the program PROMOTIF (Hutchinson & Thorton, 1995). (b) Backbone superposition of TcaXI (white), TthXI (yellow), AXI (purple), and AmiXI (cyan) subunits. Figures drawn with MOLSCRIPT (Kraulis, 1991) and rendered by Raster3D (Merritt & Murphy, 1994).
