Thiamine biosynthesis protein ApbE; Flavin transferase that catalyzes the transfer of the FMN moiety of FAD and its covalent binding to the hydroxyl group of a threonine residue in a target flavoprotein. Belongs to the ApbE family.

Part of four member fumarate reductase enzyme complex FrdABCD which catalyzes the reduction of fumarate to succinate during anaerobic respiration; FrdAB are the catalytic subcomplex consisting of a flavoprotein subunit and an iron-sulfur subunit, respectively; FrdCD are the membrane components which interact with quinone and are involved in electron transfer; the catalytic subunits are similar to succinate dehydrogenase SdhAB; Derived by automated computational analysis using gene prediction method: Protein Homology.

Part of four member succinate dehydrogenase enzyme complex that forms a trimeric complex (trimer of tetramers); SdhA/B are the catalytic subcomplex and can exhibit succinate dehydrogenase activity in the absence of SdhC/D which are the membrane components and form cytochrome b556; SdhC binds ubiquinone; oxidizes succinate to fumarate while reducing ubiquinone to ubiquinol; the catalytic subunits are similar to fumarate reductase; Derived by automated computational analysis using gene prediction method: Protein Homology.

Succinate dehydrogenase; Membrane-anchoring subunit of succinate dehydrogenase (SDH).

Fumarate hydratase; Catalyzes the reversible hydration of fumarate to (S)-malate. Belongs to the class-I fumarase family.

Ubiquinol-cytochrome c reductase iron-sulfur subunit; Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis.

Acetyl-coenzyme A synthetase; Catalyzes the conversion of acetate into acetyl-CoA (AcCoA), an essential intermediate at the junction of anabolic and catabolic pathways. AcsA undergoes a two-step reaction. In the first half reaction, AcsA combines acetate with ATP to form acetyl-adenylate (AcAMP) intermediate. In the second half reaction, it can then transfer the acetyl group from AcAMP to the sulfhydryl group of CoA, forming the product AcCoA; Belongs to the ATP-dependent AMP-binding enzyme family.

propionate--CoA ligase; Catalyzes the formation of propionyl-CoA using propionate as a substrate; PrpE from Ralstonia solanacearum can produce acetyl-, propionyl-, butyryl- and acrylyl-coenzyme A, and Salmonella enterica produces propionyl- and butyryl-coenzyme A; not expressed in Escherichia coli when grown on propionate/minimal media; ATP-dependent; Derived by automated computational analysis using gene prediction method: Protein Homology.

AckA utilizes acetate and can acetylate CheY which increases signal strength during flagellar rotation; utilizes magnesium and ATP; also involved in conversion of acetate to aceyl-CoA; also known to act on propionate; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the acetokinase family.
