Figure 2From: Analysis of substructural variation in families of enzymatic proteins with applications to protein function predictionSCs for the xylose isomerases. Xylose isomerase structures from 12 different species of bacteria and thermophilic archaea form clusters that can be mapped to the Family-level of taxonomic classification. Light gray ellipses denote automatically identified clusters. The open/closed plot characters correspond to apo/holo structures, respectively.Back to article page
