Escherichia coli 4-fluorotryptophan-substituted arginyl-tRNA synthetase was biosynthetically prepared and purified from a tryptophan auxotroph which could overproduce this enzyme. A method was developed to separate 4-fluorotryptophan from tryptophan and to determine accurately their contents in the 4-fluorotryptophan-containing proteins. It was

The derivative 4-fluorotryptophan was confirmed to have negligible fluorescence at 25 degrees C and 285 nm (tryptophan/4-fluorotryptophan quantum-yield ratio greater than 100:1). However, photolysis experiments on tryptophan and 4-fluorotryptophan, in which loss of starting material was measured by reverse-phase h.p.l.c.

Escherichia coli isolates that were tolerant of incorporation of high proportions of 4-fluorotryptophan were evolved by serial growth. The resultant strain still preferred tryptophan for growth but showed improved growth relative to the parental strain on other tryptophan analogues. Evolved

The 2.2 A crystal structure of a ternary complex formed by yeast arginyl-tRNA synthetase and its cognate tRNA(Arg) in the presence of the L-arginine substrate highlights new atomic features used for specific substrate recognition. This first example of an active

We have obtained the 470 MHz 19F NMR spectra of wild type [4-F]Trp-labeled myoglobins (MbCO, MbO2, deoxyMb, metMb, and MbCN) and hemoglobins (HbCO, HbO2, and deoxyHb), as well as those of several mutants (W7F Mb, betaW15F Hb, betaW37S Hb, and
