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)

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.

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

Bacillus subtilis strain QB928, a tryptophan-auxotroph, was serially mutated to yield strain HR15. For QB928, tryptophan functioned as a competent amino acid and 4-fluorotryptophan as merely an inferior analogue. For HR15, these roles were reversed. The tryptophan/4-fluorotryptophan growth ratio decreased

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
