Application
来自酿酒酵母的醇脱氢酶已用于测定NAD+和NADH浓度。
Biochem/physiol Actions
分子量为 141kDa 的四聚体包含了 4 个相同的亚基。每个亚基的活性位点都含有一个锌原子。每个活性位点还含有 2 个反应性巯基以及一个组氨酸残基。
等电点:5.4-5.8
最适 pH:8.6-9.0
底物:酵母乙醇脱氢酶与乙醇最易反应,它的反应活性随着醇体积增大或减小而降低。与支链醇和仲醇的反应活性也非常低。
KM(乙醇)= 2.1×10-2M
KM(甲醇)= 1.3×10-1M
KM(异丙醇)= 1.4×10-1M
抑制剂:能与游离巯基反应的化合物,包括 N-烷基马来酰亚胺和碘乙酰胺。
锌螯合剂的抑制剂,包括 1,10-菲咯啉、
8-羟喹啉、2,2′-联吡啶以及硫脲。
底物类似物抑制剂,包括 β-NAD 类似物、嘌呤和嘧啶衍生物、氯乙醇以及氟乙醇。
吸光系数:E1% = 14.6(水,280nm)

酵母醇脱氢酶1(ADH1)在葡萄糖发酵过程中催化乙醛转化为乙醇。它还可通过埃利希通路从氨基酸分解产生酒精。
Features and Benefits
干燥的酶已经在真空干燥器中储存了几周,活性几乎没有损失。根据A. Kornberg, 3描述的试验,这种酶可以冷冻保存,反复解冻而不会明显丧失活性。
Physical form
Solids containing <2% citrate buffer salts
Other Notes
在pH8.8,25℃条件下,一个单位每分钟可将1.0 μmole乙醇转化为乙醛。
