Figure 3.
Figure 3 Superposition of PNP apoenzyme with the PNP-guanine
complex, showing the gate movement, which involves a helical
transformation of residues 257-265 in the transition apoenzyme
complex. Movements of the residues Tyr249, His257 and Lys265 and
the position of ligand and sulfates can be observed. The figure
was generated with the program MOLMOL (Koradi et al.,
1996[Koradi, R., Billeter, M. & Wuthrich, K. (1996). J. Mol.
Graph. 14, 51-55.]).
