CC   -!- FUNCTION: Destroys superoxide anion radicals which are normally
CC       produced within the cells and which are toxic to biological
CC       systems. {ECO:0000250|UniProtKB:P07895}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 H(+) + 2 superoxide = H2O2 + O2; Xref=Rhea:RHEA:20696,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:15379, ChEBI:CHEBI:16240,
CC         ChEBI:CHEBI:18421; EC=1.15.1.1;
CC   -!- COFACTOR:
CC       Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC         Evidence={ECO:0000250|UniProtKB:P04179};
CC       Note=Binds 1 Mn(2+) ion per subunit.
CC       {ECO:0000250|UniProtKB:P04179};
CC   -!- SUBUNIT: Homotetramer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion matrix {ECO:0000250}.
CC   -!- PTM: Nitrated under oxidative stress. Nitration coupled with
CC       oxidation inhibits the catalytic activity.
CC       {ECO:0000250|UniProtKB:P07895}.
CC   -!- PTM: Acetylation at Lys-122 decreases enzymatic activity.
CC       Deacetylated by SIRT3 upon exposure to ionizing radiations or
CC       after long fasting (By similarity).
CC       {ECO:0000250|UniProtKB:P04179}.
CC   -!- PTM: Polyubiquitinated; leading to proteasomal degradation.
CC       Deubiquitinated by USP36 which increases protein stability.
CC       {ECO:0000250|UniProtKB:P04179}.
CC   -!- SIMILARITY: Belongs to the iron/manganese superoxide dismutase
CC       family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=BAC20354.1; Type=Erroneous initiation; Note=Translation N-terminally shortened.; Evidence={ECO:0000305};
