Application

  • Determination of the 19F NMR chemical shielding tensor and crystal structure of 5-fluoro-dl-tryptophan.: This study provides a detailed analysis of the 19F NMR chemical shielding tensor and the crystal structure of 5-Fluoro-dl-tryptophan, offering valuable insights into its electronic environment and molecular interactions. Such detailed structural characterization is crucial for the development of fluorinated drugs and biomolecules, enhancing our understanding of their interactions and functionalities (Sykes BD et al., 2007).

Biochem/physiol Actions

5-Fluoro-DL-tryptophan (5-F-TRP), a fluorine-containing analogue of tryptophan, may 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.

In our study on nutritional requirement for the hyphal growth of Schizophyllum commune, we found that a Trp- mutant could not grow in the L-Trp-supplied medium in the presence of L-Ser. Further growth studies showed that not only L-Ser but

Two fluorine-containing analogues of the cyclic AMP receptor protein (CRP) from Escherichia coli were prepared by biosynthetic incorporation of 5-fluorotryptophan (5-F-Trp) and 3-fluorotyrosine (3-F-Tyr). The 19F-n.m.r. spectrum of the [5-F-Trp]CRP showed two signals corresponding to the two tryptophan residues, and
