The absence of quinoprotein alcohol dehydrogenase in Acinetobacter calcoaceticus.
It is shown that the unusual NAD(P)+-independent quinoprotein alcohol dehydrogenase, said previously to be responsible for oxidation of ethanol during growth of Acinetobacter calcoaceticus LMD 79.39, was in fact isolated from an unidentified organism which contained cytochrome c and which has now been lost. Several genuine strains of A. calcoaceticus do not contain cytochrome c nor do they contain a quinoprotein alcohol dehydrogenase. The enzyme responsible for ethanol oxidation in these bacteria is an inducible NAD+-linked alcohol dehydrogenase.
