Protein

Fumarate hydratase class I, aerobic

Gene

fumA

Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Catalyzes the reversible hydration of fumarate to (S)-malate. Functions as an aerobic enzyme in the direction of malate formation as part of the citric acid cycle. Accounts for about 80% of the fumarase activity when the bacteria grow aerobically. To a lesser extent, also displays D-tartrate dehydratase activity in vitro, but is not able to convert (R)-malate, L-tartrate or meso-tartrate. Can also catalyze the isomerization of enol- to keto-oxaloacetate.5 Publications

Catalytic activityi

(S)-malate = fumarate + H2O.3 Publications
Keto-oxaloacetate = enol-oxaloacetate.1 Publication

Cofactori

Binds 1 4Fe-4S cluster per subunit.2 Publications

Enzyme regulationi

Is inactivated by oxygen, due to oxidation of the Fe-S cluster to its [3Fe-4S] form. Both the fumarase and the isomerase reactions are competitively inhibited by 3-hydroxy-2-nitropropionate. The isomerase reaction is also inhibited by fumarate and malate.3 Publications

Kineticsi

kcat is 3000 sec(-1) for the hydration of fumarate and 300 sec(-1) for the isomerization of enol-oxaloacetate1 Publication
