Figure 6From: VASCo: computation and visualization of annotated protein surface contactsSurface difference comparison of the active site of two enoate reductases. The active site surfaces are coloured according to surface difference values (red -3 Ã…, green +3 Ã…, yellow no difference). a) OPR1 active site surface difference to OPR3. b) OPR3 active site surface difference to OPR1.Back to article page
