Tryptophan fluorescence lifetimes in lysozyme.
Tryptophan fluorescence lifetimes at pH 2 and pH 8 have been obtained for lysozyme and for lysozyme derivatives in which tryptophan-62 or tryptophan-108 or both are nonfluorescent. The lifetimes range from about 0.5 ns to 2.8 ns for the various emitting tryptophans. The tryptophan lifetimes appear to increase with exposure of tryptophan to solvent, but intramolecular contacts, probably with cys...

15 صفحه اولThe Fluorescence Quenching of Lysozyme by Iodide and Acrylamide
Luminescence is the emission of photons from electronically excited states. The electron in the in the lowest excited singlet state (S1), has the opposite spin orientation as the second electron in the lower ground state (S0) orbital. The ground state and excited state electrons are said to be paired. Fluorescence is the emission which results from the return to the lower orbital of the excited...
متن کاملRefolding of Lysozyme Upon Interaction with ?-Cyclodextrin
Effects of ?-cyclodextrin, ?CD, on refolding of lysozyme was investigated at pH 12 employing isothermal titration calorimetry (ITC) at 300K in 30mM Tris buffer solution. ?CD was employed as an anti-aggregation agent and the heats obtained for lysozyme+?CD interactions are reported and analyzed in terms of the extended solvation model. It was indicated that there are two sets of identical and no...
متن کاملLogarithmic decay in single-particle relaxation of hydrated lysozyme powder.
We present the self-dynamics of protein amino acids of hydrated lysozyme powder around the physiological temperature by means of molecular dynamics simulations. The self-intermediate scattering functions of the amino acid residue center of mass display a logarithmic decay over 3 decades of time, from 2 ps to 2 ns, followed by an exponential alpha relaxation. This kind of slow dynamics resembles...
