Phylogenetic tree of Fur-type regulators from three cyanobacterial strains. Amino acid sequences of the three Fur-type regulators from Anabaena 7120, Synechocystis 6803, and Synechococcus 7002 were aligned using ClustalW and a phylogenetic tree was generated using (Protein alignment, BLOSUM matrix, default settings; unrooted neighbor-joining tree with branch lengths). The three respective Fur-type regulators (Fur, Zur, and PerR) from Bacillus subtilis were used as an outgroup.
