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 decarboxylase were studied in detail using acetonedried cells of B. sphaericus ATCC 245. The substrate-unspecific enzyme decarboxylates the following amino acids: valine, norvaline, leucine, 2-amino n-butyric acid, norleucine, isoleucine, methionine, alanine and phenylalanine. When two substrates are present…

Summary1.Simple aliphatic aldehydes are converted into the corresponding monoamines by Sarcina lutea ATCC 9341. Using acetone-dried cells some properties of the aminating enzyme system were studied.
Molecular characterization and analysis of the biosynthetic gene cluster for the azoxy antibiotic valanimycin
Overproduction and characterization of VlmD demonstrated that it catalyses the decarboxylation of l ‐valine, andGene disruption experiments defined the boundaries of the valanimycin gene cluster, which appears to contain 14 genes.

Summary1.Forty-seven bacterial strains were examined for their ability to form steam-volatile amines during growth in a complex medium. Twenty-one strains were found to produce a total of seven
Amine variations in faecal content in the first weeks of life of newborns in relation to breast-feeding or infant formulas
The amounts of polyamines supplied by breast milk or infant formula feeding, up to day 30 postpartum, in the faeces of newborns were much higher than in infant formula, related to distinct colonisation of amine-producing bacteria, which can be established by polyamines.


Diaminopimelate Decarboxylase of Sporulating Bacteria
The meso-diaminopimelate (DAP) decarboxylase of Bacillus licheniformis, a pyridoxal phosphate-requiring enzyme, was stabilized in vitro and exhibited Michaelis-Menten kinetics with regard to control of dipicolinic acid and spore mucopeptide biosynthesis.
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.
Decarboxylierung von L-Methionin durch Proteus vulgaris und Bacillus sphaericus
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
Oxidation of meso-2,6-diaminopimelic acid by certain sporulating species of bacteria.
SUMMARY Investigations were made of the transformations undergone by the stereoisomers of α,ɛ-diaminopimelic acid in suspensions of acetone-dried organisms of two species of sporulating bacteria,
Inhibition of leucine decarboxylase by thiol-binding reagents.
Amino Acid Metabolism in Microorganisms
Certain Streptomyces strains were found to accumulate an unknown substance in culture broth when the microorganisms were grown in the medium containing dl-methionine, which was identified as 3-methylthiopropylamine (MTPA), decarboxylated product of methionine from its melting point, chemical composition, infrared spectrum, and other properties.
