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.

The complex Re(bpy)(CO)3CN is an excited state oxidant of tyrosine upon deprotonation of the tyrosyl phenol. A series of Re(bpy-FnY)(CO)3CN complexes ([Re]-FnY: [Re]-Y, [Re]-3-FY, [Re]-3,5-F2Y, [Re]-2,3-F2Y, [Re]-2,3,5-F3Y, [Re]-2,3,6-F3Y, and [Re]-F4Y) have been prepared so as to vary the FnY*/FnY- reduction
The tracer 6-[18F]fluoro-L-m-tyrosine (FMT) was studied with regard to its biochemistry and kinetics, as well as its utility in evaluating brain dopaminergic function in primates before and after 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) treatment using positron emission tomography (PET). Plasma analysis of FMT

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

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
Physics in medicine and biology, 47(11), 1961-1977 (2002-07-11)
Physiological quantification of dynamic PET data requires the determination of an input function, preferably from plasma. A compartmental model relating a parent radiotracer, its radiolabelled metabolites and their exchange between plasma and erythrocytes is presented. This model allows for the
