Figure 13 A close-up view of the ornithine binding pocket.
Ordered water molecules are indicated by the red spheres. The
carboxylate group of ornithine interacts with the allosteric
domain while the -amino
group of the side chain forms hydrogen bonds with amino-acid
residues from the carbamoyl phosphate synthetic component.
