功能： catalytic activity:An alcohol + NAD(+) = an aldehyde or ketone + NADH.,cofactor:Binds 2 zinc ions per subunit.,miscellaneous:There are 7 different ADH's isozymes in human: three belongs to class-I: alpha, beta, and gamma, one to class-II: pi, one to class-III: chi, one to class-IV: ADH7 and one to class-V: ADH6.,polymorphism:Three alleles are known: ADH1B*1 (ADH2*1) corresponding to variant beta-1, ADH1B*2 (ADH2*2) corresponding to variant beta-2, ADH1B*3 (ADH2*3) corresponding to variant beta-3. The sequence shown is that of allele ADH1B*1. The ADH1B*2 allele frequency in orientals is approximately 75%, whereas it is less than 5% in most Caucasian populations.,polymorphism:Two main alleles are known, ADH3*1 or gamma-1 has Arg-272/Ile-350 while ADH3*2 or gamma-2 has Gln-272/Val-350. ADH3*1 is associated with a fast rate of ethanol oxidation and ADH3*2 with a slow rate.,similarity:Belongs to the zinc-containing alcohol dehydrogenase family.,subunit:Dimer of identical or non-identical chains of three types; alpha, beta and gamma.,
