We present results of time resolved fluorescence measurements performed in Tryptophan (Trp) derivatives and Trp-containing peptides in the pH range 3.0-11.0. For each compound a set of decay profiles measured in a given range of pH values was examined as

In recent years metal-enhanced fluorescence (MEF) using silver particles has been reported for a number of fluorophores emitting at visible wavelengths. However it was generally thought that silver particles would always quench fluorescence at shorter wavelengths. We now report the

This article probes the denatured state ensemble of ribonuclease Sa (RNase Sa) using fluorescence. To interpret the results obtained with RNase Sa, it is essential that we gain a better understanding of the fluorescence properties of tryptophan (Trp) in peptides.

When tryptophanyl-tRNA synthetase from Escherichia coli is allowed to react with L-tryptophan and ATP-Mg in the presence of inorganic pyrophosphatase, the fluorescence change of the reaction mixture reveals three or four sequential processes, depending on the buffer used. Quenched-flow and

The amides of L-phenylalanine, L-tyrosine and L-tryptophane decrease the melting temperatures tm of poly(A)*poly(U) and poly(I)*poly(C) double helices at low concentrations (1 mM), whereas high concentrations finally lead to an increase of tm. This dependence of the tm-values upon the
