A primary alcohol dehydrogenase has been purified fromMethylococcus capsulatus (Texas strain). The purified enzyme catalyzes the oxidation of methanol and formaldehyde to formate; other primary alcohols are oxidized to their corresponding aldehydes. Ammonium ions are required for enzyme activity. The enzyme has a molecular weight of 120,000 daltons and consists of two 62,000 molecular-weight subunits which dissociate at acidicp H. The enzyme is similar to an alcohol dehydrogenase enzyme isolated fromPseudomonas sp. M27.
