Transport of aromatic amino acids by Brevibacterium linens.
Whole metabolizing Brevibacterium linens cells were used to study the transport of aromatic amino acids. Kinetic results followed the Michaelis-Menten equation with apparent Km values for phenylalanine, tyrosine, and tryptophan of 24, 3.5, and 1.8 microM. Transport of these amino acids was optimum at pH 7.5 and 25 degrees C for phenylalanine and pH 8.0 and 35 degrees C for tyrosine and tryptoph...
متن کاملTransport of amino acids.
Before amino acids nourish the cell they must be transported a) across the intestinal mucosa and b) across the plasma membrane of the cell where they are to be used. In addition, full consideration of their economy in the animal organism must include also their entry into the liver and their resorption from the renal tubule. All of these events appear to have much in common and probably to repr...
متن کامل4 Aromatic Amino Acids in the Brain
This chapter describes the aromatic L‐amino acids tryptophan and tyrosine and the effects on tyrosine metabolism of phenylalanine. Tryptophan and phenylalanine are essential amino acids and must ultimately be derived from dietary proteins; tyrosine is obtained both from dietary proteins and from the hydroxylation of phenylalanine by phenylalanine hydroxylase (PAH). The proportions of dietary tr...
متن کاملInhibition of D-amino acid oxidase by aromatic acids.
Benzoate competes with n-amino acids for n-amino acid oxidase and thus inhibits the activity of the oxidase (l-3). Monosubstituted benzoates, depending upon the substituent, have higher and lower affinities for the oxidase than has benzoate (2). Kojic acid, a Y-pyrone, likewise competitively inhibits the oxidase (4). The present report describes the inhibition of n-amino acid oxidase by certain...

Bacteriol. 88:1590-1594. 1964.-An auxotrophic mutant of Hydrogenomonas facilis was isolated which requires tryptophan, phenylalanine, and p-aminobenzoic acid (PABA) for growth. With glucose as the main carbon and energy source, the quantitativ...
