SUCLG1 (succinate-CoA ligase GDP/ADP-forming subunit alpha) is a critical component of the succinate-CoA ligase enzyme complex, which plays an essential role in the tricarboxylic acid (TCA) cycle and mitochondrial energy metabolism. This nuclear-encoded protein localizes to the mitochondrial matrix and functions as the alpha subunit of the heterodimeric enzyme SUCLG1-SUCLA2 (GDP-forming) or SUCLG1-SUCLG2 (ADP-forming). The enzyme catalyzes the reversible conversion of succinate and CoA to succinyl-CoA, coupled with substrate-level phosphorylation to generate GTP or ATP, linking the TCA cycle to oxidative phosphorylation.
Recombinant human SUCLG1 protein is engineered for research applications, typically expressed in *E. coli* or mammalian systems to study its structural, functional, and regulatory properties. Mutations in the *SUCLG1* gene are associated with mitochondrial disorders like mitochondrial DNA depletion syndrome (MTDPS), characterized by encephalomyopathy, metabolic acidosis, and organ dysfunction. Recombinant SUCLG1 enables mechanistic investigations into how defects in succinate-CoA ligase activity impair cellular energy production, metabolite balance, and mitochondrial dynamics.
Its applications extend to modeling metabolic diseases, drug screening for mitochondrial dysfunction, and exploring links between TCA cycle defects and pathologies such as cancer, neurodegenerative diseases, and aging. Structural studies using recombinant SUCLG1 also aid in mapping mutation hotspots and designing targeted therapies.
