WebSequences in the hemerythrin-like group exhibit symmetrical traits both in sequence and structure, suggesting a possible origin of hemerythrin through a duplication and fusion event involving a primordial two-up-and-down helix motif containing a single H-HxxxE cation-coordination site (Fig. 5). This duplication resulted in an increase of the ... WebHemeritrina.
