Schematic diagram of the reductive tricarboxylic acid cycle of L. ferriphilum DSM 17947. Catalytic enzymes are indicated by numbers: 1, malate dehydrogenase (EC 1.1.1.37); 2, fumarate hydratase (EC 4.2.1.2); 3, fumarate reductase (EC 6.2.1.5); 4, succinyl-CoA synthetase (EC 6.2.1.5); 5, 2-oxoglutarate ferredoxin oxidoreductase (EC 1.2.7.3); 6, isocitrate dehydrogenase (EC 1.1.1.42); 7, aconitase hydratase 1 (EC 4.2.1.3); 8, citryl-CoA synthetase (EC 6.2.1.18); 9, citryl-CoA lyase (EC 4.1.3.34); 10, pyruvate ferredoxin oxidoreductase (EC 1.2.7.1). Key enzymes are indicated by asterisks. Fdxred, reduced ferredoxin.
