The function of superoxide dismutase (SOD) is to destroy the radicals that are normally produced within cells and are toxic to biological systems by catalysing the conversion of superoxide radicals to molecular oxygen. Three evolutionarily distinct families of SODs are known, of which the Fe/Mn-binding family is one.
Family-defining Pfam domains (at least one of these domains is present in each family member):
|Pfam domain||Pfam clan|
|PF00081||Iron/manganese superoxide dismutases, alpha-hairpin domain||-|
|PF02777||Iron/manganese superoxide dismutases, C-terminal domain||-|
