Protein

Superoxide dismutase [Mn/Fe] 2

Gene

sodM

Organism
Staphylococcus aureus (strain NCTC 8325)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

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 during the late-exponential and stationary phases of growth since it becomes a major source of activity under oxidative stress. 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 at low level of SOD activity (By similarity).By similarity

Catalytic activityi

2 superoxide + 2 H+ = O2 + H2O2.

Cofactori

Binds 1 manganese or iron ion per subunit.By similarity

Expressioni

Inductioni

Transcriptionally induced by externally generated superoxide stress in a manganese-dependent way. The presence of manganese increases SodA homodimer activity and simultaneously decreases SodM homodimer activity. This occurs primarily due to post-transcriptional effects, since the expression of the gene is independent of manganese availability in the absence of superoxide generating compounds.

Interactioni

Subunit structurei

Homodimer. Can also form a heterodimer with SodA.1 Publication

Miscellaneousi

Miscellaneous

According to PubMed:11344148 the levels of SodM activity and sodM expression are growth-phase dependent, occurring most during the late-exponential and stationary phases. This response is also dependent on the level of aeration with highest activity occurring under high aeration. SodM expression under low-aeration growth conditions is most abundant during the late-exponential phase while under high-aeration growth conditions is highest during the stationary phase.
Transcribed from a single sigmaA-type promoter (PM). Transcriptional data show an indirect repression of PM promoter by sigmaB which can also be involved in the post-transcriptional regulation of SodM homodimer activity.
