ACO2 (Aconitate Hydratase 2) is a mitochondrial enzyme belonging to the aconitase family, which plays a critical role in cellular energy metabolism and iron homeostasis. It catalyzes the reversible isomerization of citrate to isocitrate in the tricarboxylic acid (TCA) cycle, a central pathway for ATP production. Beyond its metabolic function, ACN2 also participates in iron-sulfur (Fe-S) cluster biogenesis and regulates cellular responses to oxidative stress by interacting with iron-responsive elements (IREs) in mRNA. Dysregulation of ACO2 has been linked to metabolic disorders, neurodegenerative diseases, and cancer, highlighting its biological significance.
Recombinant ACO2 protein is engineered using molecular cloning techniques, typically expressed in *E. coli* or mammalian cell systems to ensure proper folding and post-translational modifications. This recombinant form retains enzymatic activity and structural integrity, enabling researchers to study its biochemical properties, substrate interactions, and regulatory mechanisms *in vitro*. It serves as a vital tool for investigating mitochondrial dysfunction, iron metabolism anomalies, and oxidative stress pathways. Additionally, recombinant ACO2 facilitates drug discovery efforts targeting metabolic syndromes or diseases associated with Fe-S cluster deficiencies. Its applications extend to diagnostic assays, enzyme replacement studies, and structural biology (e.g., crystallography) to elucidate mechanistic details of catalysis and disease-related mutations. By providing a purified, functional version of ACO2. recombinant technology advances both basic research and therapeutic development in mitochondrial and metabolic medicine.
