Phylogenetic trees of selected pathway enzymes in A. niger and their orthologues in A. terreus. Phylogenetic trees of amino acid sequences of selected pathway enzymes in A. niger and their orthologues in A. terreus. The encoded Aspergillus niger proteins are designated with their corresponding An numbers (Anxxgxxxxx) and Aspergillus terreus proteins are designated with their corresponding ATEG numbers (ATEG_xxxxx). Proteins that are clustered together are shaded in the same colour throughout the separate classes. Phylogenetic trees were constructed using the phylogeny.fr online tool [38]. a Phylogenetic tree of known citrate synthase proteins and their orthologues in A. niger and A. terreus. Interestingly, the citrate synthase proteins from A. niger without predicted mitochondrial localization are clustered separately and no known orthologues are present in A. terreus. b Phylogenetic tree of CadA and predicted CadA-like enzymes in A. niger and A. terreus
