Protein sequence network for homologues of arylsulfatases and phosphonate monoester hydrolases, including reconstructed ancestral sequences from a maximum-likelihood phylogenetic tree.

The GraphML attributes for the edges comprise the edge weights (pairwise sequence identity, "weight"). The GraphML attributes for the nodes comprise several annotations, if available: the annotated name ("Annotation"), the source organism ("Organism"), the accessions from the Protein Data Bank ("PDB"), an accession to public sequence databases such as the NCBI GenBank ("Accession"), an annotated name for the sequence ("Name"), and the group it belongs to ("Group"). Reconstructed ancestors are labelled by an integer as "Name" and "reconstructed ancestor" as "Annotation".
