Figure 3.
Repeat units of the hemerythrin‐like domain. Internal sequence symmetry was identified by HHpredID with a probability >90. Structural superimposition of the repeat units in (A) PF0695 from Pyrococcus furiosus (PDB ID: 3CAX), and in (B) YtfE from E. coli (PDB ID: 5FNN). Sequence alignments are based on the structural superimposition of the repeat units. Aligned residues are connected by a dot. Exact matches are connected by a colon. Amino acids that participate in cation‐coordination are marked with an asterisk.
