Metabolite Identification
Common Name7-chloro-L-tryptophan
Description7-chloro-L-tryptophan is a halogenated amino acid and a member of the aromatic amino acid class. Its chemical structure features a chlorine atom substituted at the 7-position of the indole ring of L-tryptophan, which is crucial for its reactivity and biological pathways. The compound is synthesized through the chlorination of L-tryptophan, facilitated by enzymes such as tryptophan 7-halogenase (PrnA or RebH) and flavin reductase (Fre, PrnF, or RebF), with various gene combinations enhancing its production (PMID:38783320 ). In metabolic pathways, 7-chloro-L-tryptophan serves as a precursor for the biosynthesis of monodechloroaminopyrrolnitrin (MCAP) and its putative derivative, monodechloroaminopyrrolnitrin (MDAP), catalyzed by the enzyme PrnB (PMID:40827054 ; PMID:38783320 ). Additionally, it has been shown to be produced fermentatively from sugars, ammonium, and chloride salts, highlighting its potential for biotechnological applications (PMID:30579891 ). The compound is also noted for its importance in the pharmaceutical and agrochemical industries as a bioactive intermediate (PMID:30579891 ). Furthermore, KtzR can further chlorinate 7-chloro-L-tryptophan to yield 6,7-dichloro-L-tryptophan, showcasing its role in complex halogenation processes (PMID:18828589 ).
