- Protein existenceInferred from homology
- Annotation score3/5
Function
function
Involved in the TCA cycle. Catalyzes the stereospecific interconversion of fumarate to L-malate.
Miscellaneous
There are 2 substrate-binding sites: the catalytic A site, and the non-catalytic B site that may play a role in the transfer of substrate or product between the active site and the solvent. Alternatively, the B site may bind allosteric effectors.
Catalytic activity
- (S)-malate = fumarate + H2O
Pathway
Carbohydrate metabolism; tricarboxylic acid cycle; (S)-malate from fumarate: step 1/1.
