Abstract: | 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. |
