Figure 1. Cyp301a1 is a conserved insect P450.
(A) Phylogenetic analysis of Cyp301A1 and Cyp301B1 in the insect species. Values shown represent 1000 bootstrapping values. D. melanogaster (D.mel) Cyp49A1 was used as an outgroup. D.ere = D. erecta, D.sec = D. sechellia, D.sim = D. simulans, D.yak = D. yakuba, D.ana = D. ananassae, D.per = D. persimilis, D.pse = D. pseudoobscura, D.gri = D. grimshawi, D.vir = D. virilis, D.moj = D. mojavensis, D.wil = D. willistoni, A.gam = A. gambiae, N.vit = Nasonia vitripennis, A.mel = Apis mellifera T.cas = Tribolium castaneum, B.mor = Bombyx mori, P.hum = Pediculus humanis. (B) Alignment of the heme-binding domain of Cyp301A1 and Cyp301B1 from representative insect species. Conserved residues in the heme-binding domain consensus sequence (PxxxGxxxCxG) are highlighted in blue. The conserved Phenylalanine (F) in the second position (highlighted in green) in Cyp301B1 orthologs is changed to a Tyr (Y) (highlighted in red) in all Cyp301A1 orthologs.
