Figure 3
CATH wheel plot showing the population of homologous families in different fold groups, architectures and classes. The wheel is coloured according to protein class (red, mainly α; green, mainly β; and yellow, αβ). The size of the outer wheel represents the number of homologous families in CATH whilst each band in the outer wheel corresponds to a single fold family. The size of each `fold band' therefore reflects the number of homologous families having that fold. It can be seen that most fold families contain a single homologous family. The superfold families, are shown as paler bands, containing many homologous families. The inner wheel shows the population of homologous families in the different architectures.
