Protein
Superoxide dismutase [Mn] 1
Organism
Staphylococcus aureus (strain NCTC 8325)
Function
Destroys superoxide anion radicals which are normally produced within the cells and which are toxic to biological systems. May play a role in maintaining cell viability throughout all stages of growth, but may be the major SOD activity in the exponential growth-phase. Has a role in resisting external superoxide stress. Involved in acid tolerance and the acid-adaptive response. Mediates the derepression of perR regulon in the response to HOCl stress when the level of SOD activity is low.
Similarity
Belongs to the iron/manganese superoxide dismutase family.
