The results from the soluble mutants support the hypothesis that motif I interacts with galactose and that motif V plays a role in maintaining the structural integrity of the ... place in the sequence as the non-ATP ligand binding site in the other family members. Therefore it is likely that this motif forms part of the galactose-binding site. A...
