Among methylamine and/or ethylamine minus mutants of Arthrobacter P1 four different classes were identified, which were blocked either in the methylamine transport system, amine oxidase, hexulose phosphate synthase or acetaldehyde dehydrogenase. The results indicated that a common primary amine oxidase is involved in the metabolism of methylamine and(More)
The regulation of methylamine and formaldehyde metabolism in Arthrobacter P1 was investigated in carbonlimited continuous cultures. To avoid toxic effects of higher formaldehyde concentrations, formaldehyde-limited cultures were established in smooth substrate transitions from choline-limitation. Evidence was obtained that the synthesis of enzymes involved(More)
