Inhibitors:
-SH-reagents and heavy metals, such as derivatives, 4-chloromercuribenzoate, iodoacetic acid, N-substituted maleinimides, Hg²⁺, Ag⁺ and Cu²⁺.
-Complexing agents, e.g., o- phenanthroline, EDTA, oxalate.
-NAD analogs and NAD partial structures, e.g., NADP, NADH, ADP, ADP-ribose.
-Substances, which react with enzyme bound NAD, e.g., sulfite, hydroxylamine, cyanide.
-Substrate analogs, e.g., fluoroethanol.
-Oxidizers, e.g., H₂O₂ and aerial oxygen inactivate by oxidation of essential groups.
pH optimum: 9.0 (see figure)
Temperature dependence: See figure
pH stability: 6.0-8.0 (see figure)
Thermal stability: Up to +50°C (see figure)
Specificity: Alcohol dehydrogenase oxidizes primary alcohols. Isopropanol and secondary butanol are slowly oxidized, while higher secondary and tertiary alcohols do not react. Numerous aldehydes are reduced in the reverse reaction. The enzyme does not react with NADP.
Remarks:Alcohol dehydrogenase tends to show turbidity in solution at +37°C storage. Modified Alcohol dehydrogenase shows no turbidity for at least 4 weeks in solution at +37°C.", "Name": "Properties" }, { "Language": "en", "Value": "Appearance: White lyophilizate (50 mg lyophilizate contain approximately 30 mg enzyme protein,15 mg sucrose, 5 mg phosphate)
