ADH5, Human

(Alcohol dehydrogenase 5 (class III) chi polypeptide; Alcohol dehydrogenase class chi chain; Glutathione-dependent formaldehyde dehydrogenase; S-(hydroxymethyl) glutathione dehydrogenase; FDH; ADHX; ADH-3; FALDH; GSH-FDH; GSNOR; EC 1.1.1.1; EC 1.1.1.284)

ADH5 belongs to the alcohol dehydrogenase family which metabolizes a large selection of substrates, such as retinol, ethanol, other aliphatic alcohols, hydroxysteroids, and lipid peroxidation products. ADH5 has practically no activity for ethanol oxidation, but displays high activity for oxidation of long-chain primary alcohols and for oxidation of S-hydroxymethyl-glutathione, a spontaneous adduct between glutathione and formaldehyde. ADH5 enzyme is a key factor of cellular metabolism for the removal of formaldehyde, a powerful aggravating and alerting mediator which causes pharyngitis, lacrymation, rhinitis and contact dermatitis.

ADH5 Recombinant produced in E. coli is a single polypeptide chain containing 398 amino acids (1-374) and having a molecular mass of 42.3kDa. ADH5 is fused to a 24 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

Storage:
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles.
