Application


  • Amelioration of colitis through modulation of gut microbiota: The metabolite 5-Methyl-ᴅʟ-tryptophan (5-MT), derived from Angelica sinensis polysaccharides, was found to ameliorate colitis by modulating gut microbiota and the TLR4/MyD88/NF-κB signaling pathway. This suggests a potential application of 5-MT in inflammatory bowel disease research and therapy (Zou et al., 2023).

  • Enzymatic synthesis of tryptophan derivatives: A study on the one-pot enantioselective synthesis of (S)-spirobrassinin and non-natural (S)-methylspirobrassinin from amino acids highlights a method using a turnip enzyme. This research outlines a novel approach to synthesizing tryptophan derivatives, potentially useful in biochemical assays (Ryu et al., 2021).

Biochem/physiol Actions

5-Methyl-DL-tryptophan inhibits the synthesis of anthranilate compounds that are the first steps in the biosynthesis of tryptophan in Neurospora crassa. 5-Methyl-DL-tryptophan is a corepressor of the E. coli trp repressor.
5-Methyl-DL-tryptophan may be used to select genetic mutants of PS strain of Methanococcus voltae (archaebacteria). 5-Methyl-tryptophan is a repressor trp operon expression. 5-Methyl-tryptophan is a substrate for tryptophanase. 5-Methyl-tryptophan inhibits the induction of anthranilate synthase activity by elicitors in oats.

The Escherichia coli trp repressor binds to the trp operator in the presence of tryptophan, thereby inhibiting tryptophan biosynthesis. Tryptophan analogues lacking the alpha-amino group act as inducers of trp operon expression. We have used one- and two-dimensional 1H-NMR spectroscopy

Oat phytoalexins, avenanthramides, are a series of substituted hydroxycinnamic acid amides with anthranilate. The anthranilate in avenanthramides is biosynthesized by anthranilate synthase (AS, EC 4.1.3.27). Induction of anthranilate synthase activity was investigated in oat leaves treated with oligo-N-acetylchitooligosaccharide elicitors. AS

The shikimate pathway of plants mediates the conversion of primary carbon metabolites via chorismate into the three aromatic amino acids and to numerous secondary metabolites derived from them. However, the regulation of the shikimate pathway is still far from being

Gene transformation is an integral tool for plant genetic engineering. All antibiotic resistant genes currently employed are of bacterial origin and their presence in the field is undesirable. Therefore, we developed a novel and efficient plant native non-antibiotic selection system

A cDNA clone that encodes a feedback-insensitive anthranilate synthase (AS), ASA2, isolated from a 5-methyl-tryptophan (Trp) (5MT)-resistant tobacco cell line under the control of the constitutive cauliflower mosaic virus 35S promoter, was introduced into the forage legume Astragalus sinicus by
