Protein alignment of the aegerolysin family members. Sequences were retrieved from Entrez (http://www.ncbi.nlm.nih.gov/sites/gquery) and manually edited to include only the aegerolysin domain for an optimal alignment generated by M-Coffee.25,26 The alignment output was edited using GeneDoc27 conserved mode of shading, showing percentage of conservation (60%, light gray; 80%, grey; 100%, dark grey) within a column in the alignment. Consensus (boxed in red) generated by Jalview28 was used to predicit aegerolysin secondary structure. The distribution of secondary structure elements is presented bellow the protein alignment (green box-extended strand, grey line - random coil). The accession numbers of the proteins in Figure 1 are as follows: aegerolysin (gi 24636240), ostreolysin (gi 60461919), pleurotolysin_A (gi 54312022), T_versicolor (gi 90639437), H_annosum (gi 186897694), Asp-hemolysin (gi 70985747), A_clavatus (gi 121709507), A_nidulans (gi 67522192), A_niger_1 (gi 145230219), A_niger_2 (gi 145256342), A_oryzae_1 (gi 169777319), A_oryzae_2 (gi 169772307), A_oryzae_3 (gi 169785219), A_terreus (gi 115390458), N_fischeri (gi 119487614), B_cinerea (gi 116087898), C_immitis (gi 119182290), P_brasiliensis (gi 46346063), N_crassa (gi 85079504), B_vulgaris (gi 26112720), L_multiflorum (gi 46507636), R_australe (gi 158524422), P_aeruginosa_1 (gi 152985646), P_aeruginosa_2 (gi 15595320), C_bifermentans_1 (gi 2292821), C_bifermentans_2 (gi 2292820), B_thuringiensis_1 (gi 14571542), B_thuringiensis_2 (gi 49175503).
