FIG. 5. Stereo view of the interactions between residues at
pY-1 of the phosphopeptide, shown in brown, and Dok1 (a) or IRS1
(b) PTB domain. Residues involved in important interactions are
shown in ball-and-stick representation. The residues interacting
with pY-1 are represented as green; the sulfur atom is
represented in yellow.
