[Uses]

A metabolic antagonist of tryptophan
[Definition]

ChEBI: A non-proteinogenic alpha-amino acid that is tryptophan in which the hydrogen at position 5 on the indole ring is replaced by a fluoro group.
[Biological Activity]

5-Fluoro-DL-tryptophan (5-F-TRP)a fluorine-containing analogue of tryptophanmay be incorporated into proteins such as cyclic AMP receptor protein (CRP) from Escherichia coli to study changes in ligand binding. 5-F-TRP may be used as an internal reference for chromatographic analysis of tryptophan and its derivatives found in whole blood.
[Purification Methods]

Recrystallise it from EtOH, aqueous EtOH or AcOH. Also purify it by passage through a Dowex AG1x2 (acetate form) column and recrystallise the L-enantiomer (from enzymic enrichment) from H2O/EtOH, m 158-163o(dec), [] D -8.3o (c 2.5, N NaOH).
