Fig. 4. Superposition of the CPS allosteric binding
pockets with bound IMP or glutamine/inorganic phosphate. The
model described in this report is shown in black, whereas the
structure of CPS complexed with glutamine and inorganic
phosphate, as described by Thoden et al. (2), is displayed in
red. Note the nearly exact correspondence between the inorganic
phosphate and the phosphoryl moiety of the nucleotide.
