FIG. 2. Pyridoxal binding site. The molecule in the center
is the pyridoxamine bound in the PLK·AMP-PCP-pyridoxamine
complex. The surrounding residues are shown in green, and the
hydrogen bonds between the pyridoxamine and the residues are
shown as purple dashes. The corresponding residues in the
PLK·ATP complex are in blue. A comparison of these
structures reveals local conformational adjustments of the
pyridoxal binding site when the substrates binds.
