Three evolutionarily distinct families of SODs are known, of which the Mn/Fe-binding family is one. In humans, there is a cytoplasmic Cu/Zn SOD, and a mitochondrial Mn/Fe SOD. N-terminal domain is a long alpha antiparallel hairpin. A small fragment of YTRE_LEPBI matches well - sequencing error?	Domain
