一般描述
5,5,5-Trifluoro-DL-leucine, also known as trifluoroleucine, is an analog of L-leucine amino acid, often used to synthesize highly fluorinated peptides.
应用
5,5,5-trifluoroleucine can be incorporated into the coiled-coil peptides to increase their thermal stability.

We have investigated the effect of trifluoroleucine substitution on the membrane-binding and tetramerization behavior of melittin. Analogues were synthesized in which Leu 9, Leu 13, and all four intrinsic leucine residues of melittin were replaced by 5,5,5-trifluoroleucine. Both the mono-

Varied levels of fluorinated amino acid have been introduced biosynthetically to test the functional limits of global substitution on enzymatic activity and stability. Replacement of all the leucine (LEU) residues in the enzyme chloramphenicol acetyltransferase (CAT) with the analog, 5',5',5'-trifluoroleucine

Leucine uptake by Saccharomyces cerevisiae is mediated by three transport systems, the general amino acid transport system (GAP), encoded by GAP1, and two group-specific systems (S1 and S2), which also transport isoleucine and valine. A new mutant defective in both

The resistance to 5,5,5-trifluoro-DL-leucine, encoded by the dominant allele LEU4-1, was used as a selectable marker to transform laboratory and natural Saccharomyces cerevisiae strains by the lithium acetate procedure. Results of transformation of S. cerevisiae laboratory and wine natural strains

Eighteen mutants resistant to 5',5',5'-trifluoroleucine (TFL), a leucine analog, were isolated in Saccharomyces cerevisiae strains YNN281 and YNN282. The mutants were characterized genetically and clustered in two groups, one comprising all the dominant (TFL1) and the other one all the
