Decarboxylierung von L-Methionin dutch Proteus vulgaris und Bacillus sphaericus* TItOMAS HAI~T1VIA~:N ul~d ~CK~A~D BAST Pharmakognostisches Institut der Universit~t Bonn Eingegangen am 2. September 1968 Decarboxylation o/ L-Methionine in Proteus vulgaris and Bacillus sphaericus Summary. Acetone powders of Proteus vulgaris and Bacillus sphaericus ATCC245 as well as to some lower extent washed suspensions of the fungi Claviceps purpurea and Penicillium nigricans decarboxylate L-methionine to 3-methyl-mercaptopropylamine (M]VIPA). Identity of the product of decarboxylation with authentic MSVIPA 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 a substrate-unspeeific decarboxylase of neutral amino acids. The respective enzyme in P. vulgaris would be the valine/leucine.carboxylyase (E.C. 4.1.1.14) already described by ]~I~ADIUS et al. (1957).
