CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250};
CC Note=Binds 1 Mg(2+) or Mn(2+) ion per subunit. {ECO:0000250};
CC -!- SUBUNIT: Heterooligomer of catalytic and regulatory subunits.
CC {ECO:0000305|PubMed:16527867}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000269|PubMed:14671022}.
CC -!- TISSUE SPECIFICITY: Ubiquitous. Predominantly expressed in leaves.
CC {ECO:0000269|PubMed:16527867}.
CC -!- SIMILARITY: Belongs to the isocitrate and isopropylmalate
CC dehydrogenases family. {ECO:0000305}.
