CC -!- FUNCTION: Involved in the TCA cycle. Catalyzes the stereospecific
CC interconversion of fumarate to L-malate. {ECO:0000256|HAMAP-
CC Rule:MF_00743}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(S)-malate = fumarate + H2O; Xref=Rhea:RHEA:12460,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15589, ChEBI:CHEBI:29806; EC=4.2.1.2;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00743};
CC -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle; (S)-malate
CC from fumarate: step 1/1. {ECO:0000256|HAMAP-Rule:MF_00743}.
CC -!- SUBUNIT: Homotetramer. Residues from neighboring subunits contribute
CC catalytic and substrate-binding residues to each active site.
CC {ECO:0000256|ARBA:ARBA00011668}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00743}.
CC -!- MISCELLANEOUS: There are 2 substrate-binding sites: the catalytic A
CC site, and the non-catalytic B site that may play a role in the transfer
CC of substrate or product between the active site and the solvent.
CC Alternatively, the B site may bind allosteric effectors.
CC {ECO:0000256|HAMAP-Rule:MF_00743}.
CC -!- SIMILARITY: Belongs to the class-II fumarase/aspartase family. Fumarase
CC subfamily. {ECO:0000256|ARBA:ARBA00009084, ECO:0000256|HAMAP-
CC Rule:MF_00743}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
