Distribution of proteins amongst broad structural and functional classes; the distribution of the matches among the seven structural and two functional classes in single- and multi-domain proteins. The single-domain and multi-domain matches each total 100%, independently of each other. The horizontal axis indicates the seven scop classes, which are (from 1 to 7): all-alpha, all-beta, alpha/beta, alpha + beta, multi-domain, membrane, and small protein.
