應(yīng)用
Exogenous 5-fluoro-Trp is incorporated into proteins in normal protein synthesis. Since 19F is a useful reporter group, this provides a method for studying enzyme mechanisms by NMR.
生化/生理作用
5-Fluoro-Trp is nonspecifically cytotoxic. It is believed this is due to malfunctioning enzymes that have had replacements of Trp residues by 5-fluoro-Trp. However, at least one case is known where 5-fluoro-Trp substitution leads to significantly greater catalytic activity.
