CC -!- FUNCTION: Destroys superoxide anion radicals which are normally
CC produced within the cells and which are toxic to biological systems.
CC {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. {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 oxidation
CC inhibits the catalytic activity. {ECO:0000250|UniProtKB:P07895}.
CC -!- PTM: Acetylation at Lys-98 decreases enzymatic activity. Deacetylated
CC by SIRT3 upon exposure to ionizing radiations or after long fasting (By
CC similarity). {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 family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAC20355.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
