Figure 7.

The galactose molecule bound to Gal3p in the complex adopts a unique conformation. Superposition of the galactose molecules from five different galactokinase structures. Gal3p from the Gal80p–Gal3p complex structure is shown in blue, human galactokinase (PDB code: 1WUU) is shown in green, S. cerevisiae galactokinase Gal1p (PDB code: 2AJ4) is shown in light pink, Pyrococcus furious galactokinase (PDB code: 1S4E) is shown in dark pink, and Lactococcus lactis galactokinase (PDB code: 1PIE) is shown in yellow.
