SummaryAcetone powders of Proteus vulgaris and Bacillus sphaericus ATCC 245 as well as to some lower extent washed suspensions of the fungi Claviceps purpurea and Penicillium nigricans decarboxylate L-methionine to 3-methyl-mercaptopropylamine (MMPA). Identity of the product of decarboxylation with authentic MMPA was proved by chromatographic comparison and conformance of the melting points of the picrates and DNP-derivatives. It is assumed that the decarboxylation of methionine is catalyzed by…

Über eine Valin-Carboxylyase aus Bacillus sphaericus
Summary1.The occurrence of a l-valine carboxy-lyase in Bacillus sphaericus has been demonstrated. The enzyme was found to occur in four out of nine strains tested.2.Some properties of the


Zur Biogenese Flüchtiger Amine Beim Mutterkorn-Pilz Claviceps Purpurea
Summary1.Washed mycelium of saprophytically grown Claviceps purpurea decarboxylates L-leucine, but not D-leucine, to iso-amylamine. The reaction was established in an experiment using 14C-labeled
Decarboxylation of neutral amino acids in Proteus vulgaris.
The system is adaptive (inducible); the presence of either leucine, valine or isoleucine will simultaneously induce decarboxylase activity against each of the five amino acids listed above.
Neue Alkaloide aus der saprophytischen Kultur des Mutterkornpilzes von Pennisetum typhoideum Rich. 42. Mitteilung über Mutterkornalkaloide
By selection of certain strains of the ergot fungus found on Pennisetum typhoideum Rich. (a tropical millet) and modifying the substrate we succeeded in increasing the alkaloid yield in saprophytic
Über Vorkommen und Verbreitung flüchtiger Amine bei Meeresalgen
Primary amines could be identified in species of each of the three classes of algae, but an especially widespread occurrence was found in Rhodophyceae, which might be formed from labile methylamino-compounds in the course of preparation.
