FIG. 5. Superimposition of the glucose moieties of
DIMBOA-Glc in ZmGlu1 and dhurrin in SbDhr1. The glucose ring of
DIM-BOA-Glc has rotated by 60° with respect to
that of dhurrin. Consequently, the residues binding the sugar
groups O-2, O-3, and O-4 in dhurrin bind O-3, O-4, and O-6 in
DIMBOA-Glc. See also Table III. In each box, the top residue
occurs in ZmGlu1, and the bottom residue occurs in SbDhr1. Of
the 2 glutamates shown by stick representation, Glu464 occurs in
ZmGlu1, whereas Glu460 occurs in SbDhr1.
