**Background of GCDH Recombinant Protein**
Glutaroyl-CoA dehydrogenase (GCDH) is a mitochondrial enzyme critical in the metabolism of lysine, hydroxylysine, and tryptophan. It catalyzes the oxidative decarboxylation of glutaryl-CoA to crotonyl-CoA within the mitochondrial matrix, a key step in the breakdown pathways of these amino acids. Deficiency in GCDH activity leads to glutaric acidemia type I (GA-I), an autosomal recessive disorder characterized by the accumulation of toxic metabolites like glutaric acid and 3-hydroxyglutaric acid. This metabolic imbalance often results in neurological damage, particularly striatal injury, and can manifest in acute encephalopathic crises during early childhood.
Recombinant GCDH protein is produced through genetic engineering, typically using expression systems such as *E. coli*, yeast, or mammalian cells. The recombinant form retains the enzymatic activity and structural features of the native protein, enabling its use in biochemical and clinical research. Studies leveraging recombinant GCDH aim to elucidate the molecular mechanisms underlying GA-I, including the impact of disease-associated mutations on enzyme stability, substrate binding, and catalytic efficiency.
Additionally, recombinant GCDH serves as a tool for developing therapeutic strategies, such as enzyme replacement therapy (ERT) or chaperone-based treatments. It also aids in high-throughput screening of potential small-molecule drugs to restore GCDH function in patients. Structural studies using recombinant protein have provided insights into its homotetrameric architecture and cofactor (FAD) binding, facilitating targeted drug design.
Overall, GCDH recombinant protein is vital for advancing both basic science and translational applications related to GA-I, offering pathways to improved diagnostics, therapeutics, and a deeper understanding of mitochondrial metabolic disorders.
