Cladogram of the DJ-1/ThiJ/PfpI superfamily. Consensus maximum likelihood tree with branch distances corresponding to level of bootstrap support. Known structures are highlighted along with the corresponding PDB identifier. From this tree it is clear that the DJ-1 superfamily contains proteins with diverse functions and that the DJ-1 cluster is most similar to the ThiJ subgroup. Group labels are guided by the annotation of the constituent sequences (for more details see text). Unlabeled clusters had a majority of sequences with unknown or disparate function. Sequence identifiers and files for the construction of this tree can be found in the supplemental information. Numbers in parantheses indicate percentage identities; the first number identity within the group, the second is the identity with human DJ-1.
