Figure 4
LigPlot+ representation of lactose and lactulose binding in BgaR. Lactulose binding is shown on the left and lactose binding is shown on the right. The # mark in the lactulose-binding figure indicates a steric clash between one of the galactose O atoms and Tyr31. The hydrogen bonds made by lactose are shorter/stronger than those made by lactulose. This figure was produced using LigPlot+ (Laskowski & Swindells, 2011). |
