A nicotinamide adenine dinucleotide-linked dehydrogenase has been partially purified from a mutant of Escherichia coli K-12 able to grow on l-1,2-propanediol as carbon and energy source. This enzyme catalyzes the dehydrogenation at carbon 1 of l-1,2-propanediol, glycerol, 1,3-propanediol, ethylene glycol, and ethyl alcohol. The purified protein requires added ferrous or managanous ions. The V(max) and the apparent K(m) for a given substrate vary with the particular metal used.
一种烟酰胺腺嘌呤二核苷酸连接的脱氢酶已从大肠杆菌K-12的一个突变体中部分纯化出来,该突变体能够以l-1,2-丙二醇作为碳源和能源生长。这种酶催化l-1,2-丙二醇、甘油、1,3-丙二醇、乙二醇和乙醇在碳1位的脱氢反应。纯化后的蛋白质需要添加亚铁离子或锰离子。给定底物的V(max)和表观K(m)会因所使用的特定金属而有所不同。
