RT "Molecular cloning and chromosomal assignment of the porcine methylmalonyl-
RT CoA mutase gene.";
RL Submitted (AUG-2002) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes the reversible isomerization of methylmalonyl-CoA
CC (MMCoA) (generated from branched-chain amino acid metabolism and
CC degradation of dietary odd chain fatty acids and cholesterol) to
CC succinyl-CoA (3-carboxypropionyl-CoA), a key intermediate of the
CC tricarboxylic acid cycle. {ECO:0000250|UniProtKB:P22033}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(R)-methylmalonyl-CoA = succinyl-CoA; Xref=Rhea:RHEA:22888,
CC ChEBI:CHEBI:57292, ChEBI:CHEBI:57326; EC=5.4.99.2;
CC Evidence={ECO:0000250|UniProtKB:P22033};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:22889;
CC Evidence={ECO:0000250|UniProtKB:P22033};
CC -!- COFACTOR:
CC Name=adenosylcob(III)alamin; Xref=ChEBI:CHEBI:18408;
CC Evidence={ECO:0000250|UniProtKB:P22033};
CC -!- ACTIVITY REGULATION: Inhibited by itaconyl-CoA, a metabolite that
CC inactivates the coenzyme B12 cofactor. {ECO:0000250|UniProtKB:P22033}.
CC -!- SUBUNIT: Homodimer. Interacts (the apoenzyme form) with MMAA; the
CC interaction is GTP dependent. {ECO:0000250|UniProtKB:P22033}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion matrix
CC {ECO:0000250|UniProtKB:P22033}. Mitochondrion
CC {ECO:0000250|UniProtKB:P22033}. Cytoplasm
CC {ECO:0000250|UniProtKB:P22033}.
CC -!- SIMILARITY: Belongs to the methylmalonyl-CoA mutase family.
CC {ECO:0000305}.
