Succinate dehydrogenase membrane anchor/cytochrome b subunit.

Succinate dehydrogenase cytochrome b small subunit.

NADH-ubiquinone dehydrogenase chain C,D; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient; In the N-terminal section; belongs to the complex I 30 kDa subunit family.

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

Glycine cleavage system protein P; The glycine cleavage system catalyzes the degradation of glycine. The P protein binds the alpha-amino group of glycine through its pyridoxal phosphate cofactor; CO(2) is released and the remaining methylamine moiety is then transferred to the lipoamide cofactor of the H protein; Belongs to the GcvP family.

Putative alpha-ketoglutarate dehydrogenase (E1 subunit); Observed by proteomics; Citation: Proteomics from VerBerkmoes et al. (2003) unpublished.

succinyl-coA synthetase beta chain; Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of either ATP or GTP and thus represents the only step of substrate-level phosphorylation in the TCA. The beta subunit provides nucleotide specificity of the enzyme and binds the substrate succinate, while the binding sites for coenzyme A and phosphate are found in the alpha subunit.

Cytochrome b/c1 precursor; 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.
