Fig 2. Phylogenetic analyses of CS/DS 4-O- and 6-O-sulfotransferases (A) and other CS/DS modification enzymes (B).

The consensus neighbor-joining trees were calculated with 1000 bootsrap replicates. Zebrafish orthologues are marked with grey shadow. Species names are abbreviated as hs, human; mm, mouse; dr, zebrafish, and ga, stickleback. The accession numbers are listed in the Table 1.
