Frequency of occurrence of PROSITE motifs within the folds in the CATH database. Each column represents the accumulation of the number of folds with an increase of the number of functionally important motifs (i.e., SFM ≥ 1.0). Out of the 813 folds included in the current CATH database, 550 (67.6%) folds were found to contain at least one important PROSITE motif. About 505 (61.8%) of the CATH folds have a number of important motifs in the range 1–4, while the maximum number of important motifs occurring within one CATH fold was found to be 105, occurring in the Rossman-type fold.
