The microbial oxidation of methanol. The alcohol dehydrogenase of Pseudomonas sp. M27.


ABSTRACT: 1. No primary hydrogen acceptor other than phenazine methosulphate has been found for the alcohol dehydrogenase from Pseudomonas sp. M27. 2. None of a wide range of vitamins or cofactors has any effect on the activity of the enzyme. 3. The enzyme is far less sensitive to metal-chelating agents and thiol reagents than are other alcohol dehydrogenases. 4. Methanol is oxidized at least as fast as other alcohols by this enzyme and its well-defined substrate specificity is different from that of other alcohol dehydrogenases. Only primary alcohols are oxidized; the general formula for an oxidizable substrate is R.CH(2).OH, where R may be H or [Formula: see text] 5. Whole organisms oxidize only those alcohols that are oxidized by the isolated enzyme.
