Figure 3 .

Maize BX2-5 protein alignment. P450 motifs are indicated in purple and the 6 SRSs localizations are indicated in orange. Sites potentially under positive selection according to the MA model from codeml analyses are in blue. Sites under type I functional divergence are in grey and sites under type II functional divergence are in pink. The 13 putative helices are marked in dotted boxes. Arrows indicate ten potentially important sites for the substrate specificity of each protein. Red highlighted sites represent the four residues (Leu253, Ala341, Thr345 and Ile527) in contact with indole according to docking results (AutoDock4).
