Structural Characteristics of Novel Protein Folds
Figure 1
The saturation of Smotifs over time.
Each curve corresponds to one of the four Smotifs categories (purple (strand-strand), green (strand-helix), blue (helix-helix) and red (helix-strand)). The cumulative distribution on the plot is obtained by summing the first appearances of Smotifs in 324 geometrical definitions as a function of time.
