Protein

Succinate--CoA ligase [ADP-forming] subunit beta, mitochondrial

Gene

SUCLA2

Organism
Homo sapiens (Human)
Status
Unreviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

ATP-specific succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of ATP 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.UniRule annotation

Catalytic activityi

ATP + succinate + CoA = ADP + phosphate + succinyl-CoA.UniRule annotation

Cofactori

Mg2+UniRule annotationNote: Binds 1 Mg2+ ion per subunit.UniRule annotation

Pathwayi: tricarboxylic acid cycle

This protein is involved in step 1 of the subpathway that synthesizes succinate from succinyl-CoA (ligase route).UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
