General Information

General Information Comment Organism
physiological function manganese superoxide dismutase enzymes catalyze superoxide disproportionation by a mechanism that is more complex than those of the other SOD types. In particular the reduction of superoxide can proceed via one of two pathways. One pathway dominates when the O2- concentration is low relative to the enzyme concentration, and the other pathway dominates when the ratio [O2-]/[MnSOD] is high, overview Saccharomyces cerevisiae
