**Background of ADH5 Recombinant Protein**
Alcohol dehydrogenase 5 (ADH5), also known as glutathione-dependent formaldehyde dehydrogenase (FDH), is a member of the alcohol dehydrogenase (ADH) enzyme family. It plays a critical role in cellular detoxification by catalyzing the oxidation of formaldehyde, a toxic byproduct of metabolic processes, into formate using glutathione (GSH) as a cofactor. This reaction is essential for mitigating formaldehyde-induced DNA damage and maintaining cellular homeostasis. ADH5 is ubiquitously expressed in human tissues, particularly in the liver, kidneys, and brain, underscoring its broad physiological relevance.
Structurally, ADH5 belongs to the medium-chain dehydrogenase/reductase (MDR) superfamily. Unlike other ADH isoforms involved in ethanol metabolism, ADH5 exhibits unique substrate specificity for formaldehyde and S-nitrosoglutathione (GSNO), linking it to nitric oxide metabolism and redox signaling. Its active site contains a conserved zinc ion, critical for catalytic activity, and a distinct binding pocket that accommodates GSH-adducted substrates.
Recombinant ADH5 protein is produced via heterologous expression systems, such as *E. coli* or mammalian cell cultures, enabling high-yield purification for research and therapeutic applications. Its recombinant form retains enzymatic activity and stability, making it a valuable tool for studying formaldehyde detoxification pathways, oxidative stress responses, and GSNO regulation. Additionally, ADH5 has garnered interest in biomedical research for its potential role in cancer (due to formaldehyde’s carcinogenicity) and neurodegenerative diseases linked to oxidative damage.
In summary, ADH5 recombinant protein serves as a pivotal reagent for exploring detoxification mechanisms, redox biology, and disease pathology, bridging fundamental biochemistry with translational applications.
