CAS: 9031-72-5.
Grade: BR.
Molecular weight: ~ 141000 (four subunits).
Vitality: ≥ 300 units/mg protein.
Definition of activity: One unit will convert 1.0 μ mole of ethanol to acetaldehyde per min at pH 8.8 at 25 ℃.
Protein: ≥ 90% E1% Compact 280.
Isoelectric point Isoelectric point:5.4~5.8.
Optimal pH:8.6~9.0.
Extinction Coefficient:E1% = 14.6 (water, 280nm).
Properties: White or yellowish brown powder.
Yeast extract, a zinc-containing enzyme.
Its molecule is composed of two subunits, one of which is located in the active center of the enzyme, and the other plays a role in stabilizing the quaternary structure.
Suitable for conventional determination of β-NAD, β-NADH, ethanol and acetaldehyde.
Purpose: biochemical research.
In the presence of coketone I, it catalyzed the dehydrogenation of some primary or secondary alcohols, aldehydes and ketones, and the dehydrogenation rate of n-butyraldehyde, cinnamaldehyde and benzaldehyde was higher than that of acetaldehyde.
The removed hydrogen is accepted by NAD, making it a reduced coenzyme I.
In the process of alcohol production by yeast fermentation, the last step is to reduce acetaldehyde to ethanol catalyzed by this enzyme.
Storage:-20 ℃
