Fig 5.

Structural alignment of the active sites of Blon_2336 and TM0306 in complex with fucose. Blon_2336 is shown in cyan, and TM0306 is shown in green-yellow. All active site residues and the fucose from the TM0306/fucose complex are drawn in stick format. The residues from Blon_2336 and TM0306 are labeled in blue and orange, respectively. Equivalent residues from two molecules are paired together. Some visible strands from the (β/α)₈ barrel are labeled in black. The tyrosine shown in Fig. 4 is approximately at the position of the fucose in this figure, and it is not shown for the sake of clarity.
