FIGURE 3. A comparison of human galactokinase versus GalNAc
kinase. The human forms of galactokinase and GalNAc kinase
differ in three specific regions labeled A, B, and C and
indicated by the blue ribbons in a. A superposition of the sugar
binding regions for these enzymes is given in b. The yellow
bonds correspond to GalNAc kinase, with the sugar ligand
depicted in aquamarine. The white bonds correspond to
galactokinase, with the sugar ligand highlighted in magenta. The
red and black labels correspond to residues in galactokinase and
GalNAc kinase, respectively. Coordinates for the human
galactokinase were from this laboratory (Protein Data Bank
accession number 1WUU [PDB]
).
