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

UniprotKB/SwissProt ID: Q9Z2I9 (Q9Z2I9)

Gene Name: Sucla2

Organism: Mus musculus (Mouse)

Function: 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

Protein Subcellular Localization: Mitochondrion
