Figure 2. The variation of RMSDs and sequence identity between seven-bladed β-propeller proteins.
The data points for the comparison between WD-WD proteins are coloured as red, and the green circles represent superimpositions between two non-WD proteins as well as between WD and non-WD proteins. The data shows clear structural conservation of the WD40 superfamily amongst all other seven-bladed β-propellers. RMSD has been calculated based on Cα atom positions.
