Phylogenesis of AOX proteins in vertebrates. The rooted circular phylogenetic tree was generated from the available vertebrate AOX protein sequences. The phylogenetic tree consists of all the vertebrate AOX proteins whose structure could be predicted from the cloning of the corresponding cDNAs or deduced from genome sequencing data. The bootstrap values for the most primitive branches of the tree are shown. The position of the XDH sequences in the tree is shown as a reference without an illustration of the corresponding dendrogram. The tree consists of 148 sequences covering at least 80 % of the expected AOX polypeptide lengths to account for sequencing gaps in incomplete genomes
