Biochemical properties

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.

Allergens from this family

Mn-binding superoxide dismutases from plants and fungi were identified as cross-reactive allergens [1, 2].
