Phylogenetic tree of ureohydrolases. For construction of the tree, selected sequences from eubacteria, fungi, plants, and animals were used in addition to the cyanobacterial sequences given (Tables 3 and 4). For details on the non-cyanobacterial sequences see Sekowska et al. [37] and Chen et al. [28]. Details on the cyanobacterial sequences are given (Tables 5, 6, and 9).
