(A) Sequence alignment of Pex11A proteins from various organisms. The alignment was performed with Clustal W module in MEGA software vision 5 and formatted by GeneDoc (http://www.psc.edu/biomed/genedoc). The identical amino acids are highlighted with black background, the conserved residues with dark gray background, and the similar amino acids with light gray background. The putative amphipathic helices are underlined with black arrows, and hydrophobic regions with hollow arrows. (B) The Neighbor-joining phylogenetic tree of Pex11 proteins constructed using MEGA software. The distance scale represents the differences between the sequences, with 0.1 indicating a 10% difference. Af, Aspergillus fumigatus; An, A. nidulans; Ao, A. oryzae; At, Arabidopsis thaliana; Gz, Gibberella zeae; Hs, Homo sapiens; Mo, M. oryzae; Nc, N. crassa; Pc, P. chrysogenum; Sc, S. cerevisiae.
