NameL-Tryptophan
SpeciesSaccharomyces cerevisiae
StrainBaker's yeast
DescriptionTryptophan (abbreviated as Trp or W) is an alpha-amino acid. The L-isomer is one of the 22 proteinogenic amino acids, i.e., the building blocks of proteins. It is classified as a nonpolar, aromatic amino acid, because of the hydrophobic nature of the indole side chain. L-Tryptophan is an electrically neutral amino acid. Tryptophan is synthesized from shikimic acid or anthranilate. The latter condenses with phosphoribosylpyrophosphate (PRPP), generating pyrophosphate as a by-product. After ring opening of the ribose moiety and following reductive decarboxylation, indole-3-glycerinephosphate is produced, which in turn is transformed into indole. In the last step, tryptophan synthase catalyzes the formation of tryptophan from indole and the amino acid serine. S. cerevisiae degrade the aromatic amino acids (tryptophan, phenylalanine, and tyrosine) via the Ehrlich pathway. This pathway consists of 3 steps: 1) deamination of the amino acid to the corresponding alpha-keto acid; 2) decarboxylation of the resulting alpha-keto acid to the respective aldehyde; and, 3) reduction of the aldehyde to form the corresponding long chain or complex alcohol, known as a fusel alcohol or fusel oil. Fusel alcohols are important flavor and aroma compounds in yeast-fermented food products and beverages. The primary aminotransferase in tryptophan degradation is postulated to be Aro9p. In vitro studies demonstrated that Aro9p is active with phenylpyruvate, pyruvate, or p-hydroxyphenylpyruvate, but not 2-oxoglutarate as the amino acceptor. Aro9p is induced by aromatic amino acids and is subject to nitrogen regulation.
