M-Fluorotyrosine (m-Fluoro-DL-tyrosine) may be substituted for tyrosine in the biosynthesis of proteins such as β-galactosidases (Escherichia coli), bacteriorhodopsin and intestinal microvillar enzymes, eg. aminopeptidase N, to study the effect of halogenated tryosines on the proteins properties.

Fluorine NMR is a useful tool to probe protein folding, conformation and local topology owing to the sensitivity of the chemical shift to the local electrostatic environment. As an example we make use of (19)F NMR and 3-fluorotyrosine to evaluate

An Escherichia coli tyrosine auxotroph (MR1) with an inducible lacZ was generated by mutagenesis. Of several tyrosine derivatives tested, only m-fluorotyrosine supported the growth of this mutant and allowed synthesis of active beta-galactosidase. The pH profiles of the beta-galactosidase that
Incorporation of 3-fluorotyrosine and site-specific mutagenesis has been utilized with Fourier transform infrared (FTIR) spectroscopy and x-ray crystallography to elucidate active-site structure and the role of an active-site residue Tyr34 in human manganese superoxide dismutase (MnSOD). Calculated harmonic frequencies at

The structure of the tetradeca-(3-fluorotyrosyl) M1-1 GSH transferase (3-FTyr GSH transferase), a protein in which tyrosine residues are globally substituted by 3-fluorotyrosines has been determined at 2.2 A resolution. This variant was produced to study the effect on the enzymatic

A set of N-acylated, carboxyamide fluorotyrosine (F(n)()Y) analogues [Ac-3-FY-NH(2), Ac-3,5-F(2)Y-NH(2), Ac-2,3-F(2)Y-NH(2), Ac-2,3,5-F(3)Y-NH(2), Ac-2,3,6-F(3)Y-NH(2) and Ac-2,3,5,6-F(4)Y-NH(2)] have been synthesized from their corresponding amino acids to interrogate the detailed reaction mechanism(s) accessible to F(n)()Y*s in small molecules and in proteins. These Ac-F(n)()Y-NH(2)
