Protein

Succinyl-CoA ligase [ADP/GDP-forming] subunit alpha, mitochondrial

Gene

SUCLG1

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Catalyzes the ATP- or GTP-dependent ligation of succinate and CoA to form succinyl-CoA. The nature of the beta subunit determines the nucleotide specificity (By similarity).By similarity

Catalytic activityi

GTP + succinate + CoA = GDP + phosphate + succinyl-CoA.
ATP + succinate + CoA = ADP + phosphate + succinyl-CoA.
