Incorporation of the unnatural amino acid L-(7-hydroxycoumarin-4-yl)ethylglycine (7-HC) is a powerful and reliable approach for the preparation of fluorescently labeled proteins. The growing popularity of this valuable amino acid prompted us to pursue an improved protocol for its synthetic preparation.

As newly synthesized proteins emerge from the ribosome, they interact with a variety of cotranslational cellular machineries that facilitate their proper folding, maturation, and localization. These interactions are essential for proper function of the cell, and the ability to study

The fluorescent amino acid l-(7-hydroxycoumarin-4-yl) ethylglycine 1 has been genetically encoded in E. coli in response to the amber TAG codon. Because of its high fluorescence quantum yield, relatively large Stoke's shift, and sensitivity to both pH and polarity, this

The site-specific incorporation of unnatural amino acids (UAAs) into proteins in bacteria is made possible by the evolution of aminoacyl-tRNA synthetases that selectively recognize and aminoacylate the amino acid of interest. Recently we have discovered that some of the previously

Two fluorescent amino acids, including the novel fluorescent species 4-biphenyl-l-phenylalanine (1), have been incorporated at positions 17 and 115 of dihydrofolate reductase (DHFR) to enable a study of conformational changes associated with inhibitor binding. Unlike most studies involving fluorescently labeled
