sucg-1

Gene
sucg-1
Protein
Succinate--CoA ligase [GDP-forming] subunit beta, mitochondrial
Organism
Caenorhabditis elegans
Length
415 amino acids
Function
GTP-specific succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of 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.
Similarity
Belongs to the succinate/malate CoA ligase beta subunit family. GTP-specific subunit beta subfamily.
