Figure 3. Diagrams of the hydrogen bonding networks in the
active site of (a) subunit A and (b) subunit B with the Grb2 SH2
domain represented in cartoon, ligand-binding residues in bonds
with grey carbon atoms, and ligands in ball-and-stick with green
carbon atoms. Hydrogen bonds are in cyan broken lines and
intramolecular bonds in red. Selected atoms of S1s are labeled
in red.
