Figure 4

Tertiary structure alignments. The upper left image sketches the 3-dimensional structure of Escherichia coli hydrogenase maturating endopeptidase HybD; [34]. A yellow ball represents the bound nickel ion. The deduced amino acid sequences of the putative cyanobacterial endopeptidases were aligned to this structure using SWISS-MODEL [5355]. The nickel binding amino acid residues are explicitly drawn as sticks. Alpha helices and beta sheets are sketched as rods and flat arrows, respectively. E. coli HybD: Escherichia coli HybD [34], p73102: Nostoc punctiforme ATCC 29133/PCC 73102 HupW, p7120: Anabaena PCC 7120 HupW, x7120: Anabaena PCC 7120 HoxW
