Long-Lived Termite Queens Exhibit High Cu/Zn-Superoxide Dismutase Activity

Figure 1

Alignment and structure conservation of Cu/Zn-SOD sequences. Multiple sequence alignment of Homo sapiens, Mus musculus, Caenorhabditis elegans, Drosophila melanogaster, Zootermopsis nevadensis, and Reticulitermes speratus. The signal cleavage site is indicated by a grey box. Conserved functional residues are highlighted in bold characters in grey (circled C = copper-binding site; circled Z = zinc-binding site; circled C, circled Z = copper- and zinc-binding sites; and $ = intrasubunit disulphide bridge site). SOD signature sequences are denoted in blocks with #.
