Mapping of evolutionary rates on USP structures in four extant groups of insects. Site-specific dN/dS were projected onto the crystal structure of the USP LBD domain of Tribolium (2NXX) for Blattaria (A) and Tenebrionidae (B), of Drosophila (1HG4) for Diptera (C) and of Heliothis (1R1K) for Lepidoptera (D). The values are distributed along a colour scale from blue (low dN/dS) to red (high dN/dS). Sequences not available for the estimation of evolutionary rates are in white.
