[Growth inhibition by phenylalanine and tyrosine--metabolism of phenylalanine in Flavobacterium devorans (author's transl)]. 1980

G Krauss, and R Süssmuth, and F Lingens

Growth of a chloramphenicol-resistant mutant of Flavobacterium devorans (F. devorans r) was inhibited by L-phenylalanine and L-tyrosine and furthermore by L-tryptophan, 4-amino-benzoate, anthranilate and homogentisate. The inhibitionwas reversed partially by simultaneous addition of aromatic amino acids and 4-amino-benzoate. After cultivating F. devorans r in a glucose-minimal medium containing L-phenylalanine, the metabolites L-tyrosine, 4-hydroxyphenylpyruvate, 4-hydroxyphenylacetate, 4-hydroxybenzaldehyd, 4-hydroxybenzoate, homogentisate and anthranilate were found. Growth inhibition and a hypothetical degrading pathway of phenylalanine are discussed.

Dose Response Relationship, Drug,Dose-Response Relationships, Drug,Drug Dose-Response Relationship,Drug Dose-Response Relationships,Relationship, Drug Dose-Response,Relationships, Drug Dose-Response
D005417 Flavobacterium A genus of gram-negative, aerobic, rod-shaped bacteria widely distributed in SOIL and WATER. Its organisms are also found in raw meats, MILK and other FOOD, hospital environments, and human clinical specimens. Some species are pathogenic in humans.
D014364 Tryptophan An essential amino acid that is necessary for normal growth in infants and for NITROGEN balance in adults. It is a precursor of INDOLE ALKALOIDS in plants. It is a precursor of SEROTONIN (hence its use as an antidepressant and sleep aid). It can be a precursor to NIACIN, albeit inefficiently, in mammals.
