Solenoid motif from structure alignment. (a) Automatically detected solenoid units of a Leucine Rich Repeat domain (1DFJ-I) with arbitrary solenoid unit coloring. The middle inset shows all units superimposed after multiple-structure alignment with POSA. The consensus motif determined for the structurally aligned units is displayed on the right. The next two rows display the same results for (b) an Armadillo repeat (1M8Z-A) and (c) an Ankyrin repeat (3B95-A).
