Figure 1.
Figure 1. I domain secondary structure and conformational
comparison. (a) Ribbon diagram of the CD11b I domain with Mg2+
ion bound at the C-terminal end of the mostly parallel b sheet
(green). The seven a helices are shown in red. The Mg2+ ion
(pink sphere) is coordinated by the conserved residues Ser142,
Ser144 and Asp242, which are shown in ball-and-stick
representation. (b) Superimposed ribbon diagrams of the majority
conformation of the CD11b I domain (red) and the 1ido crystal
structure (green). The different positions of Phe275 and Phe302
(ball-and-stick representation) are indicated. The Mg2+ ions are
indicated by the pink and green spheres. (The figures were
prepared using MOLSCRIPT [82] and rendered using RASTER3D [83].)
