Electron transfer flavoprotein (alpha subunit); The electron transfer flavoprotein serves as a specific electron acceptor for other dehydrogenases. It transfers the electrons to the main respiratory chain via ETF-ubiquinone oxidoreductase (ETF dehydrogenase) (By similarity).

3-hydroxybutyryl-CoA dehydrogenase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme; Belongs to the 3-hydroxyacyl-CoA dehydrogenase family.

Degradative acetoacetyl-CoA thiolase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the thiolase-like superfamily. Thiolase family.

Electron transfer flavoprotein (beta subunit); The electron transfer flavoprotein serves as a specific electron acceptor for other dehydrogenases. It transfers the electrons to the main respiratory chain via ETF-ubiquinone oxidoreductase (ETF dehydrogenase) (By similarity).

enoyl-CoA hydratase; Involved in the degradation of long-chain fatty acids.

Putative Methylglutaconyl-CoA hydratase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme; Belongs to the enoyl-CoA hydratase/isomerase family.

acetyl-CoA C-acyltransferase; Involved in the degradation of long-chain fatty acids; Belongs to the thiolase-like superfamily. Thiolase family.

2-methylcitrate dehydratase; Involved in both the tricarboxylic acid (TCA) and methylcitric acid cycles. Has both 2-methylcitrate dehydratase and citrate dehydratase activities. Catalyzes the dehydration of 2-methylcitrate (2-MC) to yield 2-methyl-cis-aconitate, and the dehydration of citrate to yield cis-aconitate. Cannot form isocitrate. Uses either (2S,3R)- or (2R,3S)-2-methylcitrate.

2-methylcitrate synthase/citrate synthase III; Involved in both the tricarboxylic acid (TCA) and methylcitric acid cycles. Has both 2-methylcitrate synthase and citrate synthase activities. Catalyzes the condensation of propionyl-CoA and oxaloacetate to yield 2-methylcitrate (2-MC) and CoA, and the condensation of acetyl-CoA and oxaloacetate to yield citrate and CoA. Has 2.3-fold higher activity as a 2-methylcitrate synthase. Catalyzes the formation of either (2S,3R)- or (2R,3S)-2-methylcitrate.
