**Background of Recombinant Human SQRDL Protein**
Recombinant human SQRDL (sulfide quinone reductase-like) protein is a genetically engineered variant of the endogenous SQRDL enzyme, which plays a critical role in cellular sulfide metabolism. SQRDL is a mitochondrial protein involved in the oxidation of hydrogen sulfide (H₂S), a gaseous signaling molecule that regulates oxidative stress, inflammation, and apoptosis. It catalyzes the transfer of electrons from sulfide to coenzyme Q10 (CoQ10) in the mitochondrial electron transport chain, linking sulfide metabolism to cellular energy production.
Structurally, SQRDL contains a flavin-binding domain and conserved cysteine residues critical for its enzymatic activity. Dysregulation of SQRDL has been implicated in pathological conditions, including neurodegenerative diseases, cardiovascular disorders, and cancer, highlighting its importance in maintaining redox homeostasis. Recombinant SQRDL is typically produced using *E. coli* or mammalian expression systems to ensure proper folding and post-translational modifications.
Research on recombinant SQRDL focuses on elucidating its biochemical mechanisms, interactions with other sulfur-metabolizing enzymes (e.g., cystathionine γ-lyase), and therapeutic potential in diseases linked to H₂S imbalance. Its applications span drug discovery, disease modeling, and mechanistic studies, offering insights into mitochondrial dysfunction and oxidative stress-related pathologies.
