Figure 9

Proportion of proteins corresponding to given structurally conserved sites coverage. This figure shows structural coverage variation of NMF, original PPA, block random, and point random basis vectors. The x-axis represents the detection ratio of structurally conserved regions, and the y-axis the proportion of proteins. MUSTANG is used for multiple structural alignments, from which we define structurally conserved regions as regions that are aligned for more than 95% Figure indicates that NMF basis vectors match with structurally conserved regions more than other vectors.
