Figure 2From: ELISA: Structure-Function Inferences based on statistically significant and evolutionarily inspired observationsProtein Domain Universe Graph (PDUG). Nodes are structural templates and edges are 3-d comparisons of these templates. A large cluster of TIM barrel domains is shown here. Edges are unweighted in the picture because this cluster was computed by taking only those structures that are similar to each other by more than Zc = 9.Back to article page
