Figure 1. Overall Structure of the I1 Ig Domain(a) Ribbon
representation. b strands of the sheets ABDE and the A'CC'FG are
color coded in pink and cyan, respectively. The two loops B-C
and F-G, close to the N terminus, are colored in light green and
dark green, respectively. The two loops A'-B and E-F, close to
the C terminus, are colored in orange and brown,
respectively.(b) Same presentation as (a) but tilted. The
disulphide bridge connecting residues 37 (b strand C) and 62 (b
strand E) is shown in ball-and-stick representation. The 3
tryptophan residues (W39, W54, and W56) surrounding the
disulphide bridge are also included.(c) Stereoview of the
2F[o]-F[c] (a[calc]) electron density map of the disulphide
bridge region contoured at 1.5 s
