(a) Positions of D1067, D1090 and D1091. These three residues are shown in red. The galactose-binding-like domain is shown in blue. The enlarged view is shown at right. (b) Docking simulation results using a nigerose molecule. Left: the nigerose molecule is shown with sphere. Right: the glutamate triad is shown with stick representation, and Ca2+ is shown with a yellow sphere. Protein Cα trace is shown with green line. Substrate-binding pocket is indicated with a dashed yellow circle.
