Steady-state fluorescence measurements on the deoxytrinucleotides (5')dTp2APpA(3') and (5')dAp2APpA(3') show a temperature-dependence and a viscosity-dependence for energy transfer that qualitatively differ from those seen in our previous study of ch

The formation of all major intermediates in the reaction catalyzed by the citrate synthase from Thermoplasma acidophilum is accompanied by changes in tryptophan fluorescence. The largest change is the strong quenching observed on formation of the bin

Tryptophan residues have been introduced into two domains of the human U1A protein to probe solution dynamics. The full length protein contains 282 residues, separated into three distinct domains: the N-terminal RBD1 (RNA Binding Domain I), consistin
