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 tryptophan-auxotrophic Bacillus subtilis LC33 mutant strain utilizes either tryptophan or 4-fluorotryptophan for growth. Proteins therefore could be isolated from these cells in either tryptophan-containing or 4-fluorotryptophan-containing forms. Since 4-fluorotryptophan is non-fluorescent, tryptophan fluorescence would be suppressed in the 4-fluorotryptophan-containing

Clamp proteins confer processivity to the DNA polymerase during DNA replication. These oligomeric proteins are loaded onto DNA by clamp loader protein complexes in an ATP-dependent manner. The mechanism by which the trimeric bacteriophage T4 clamp protein (the 45 protein)

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
