Mechanisms of Tryptophan Fluorescence Shifts in Proteins

Artificial photosynthesis: molecular systems for catalytic water oxidation.

Publisher Summary Hydration can be considered a process of adding water incrementally to dry protein, until a level of hydration is reached beyond which further addition of water produces no change and only dilutes the protein. The hydration process has several stages and an end point, reflected similarly in different types of measurements. Time-average measurements appear to have a common pattern and most closely fit a single picture of the process. Dynamic measurements sometimes show a dependence on hydration level that lies outside the common pattern of the time-average results. The chapter summarizes the literature that bears on the protein hydration process and the hydration shell, categorized by type of measurement, and provides picture of the hydration process and the hydration shell and an assessment of the ways in which the hydration shell may modulate enzyme and other protein functions. The percolation model is discussed that focuses on the long-range connectivity established at a threshold coverage of a surface or volume with conducting or otherwise functional elements.

Electron transfer : from isolated molecules to biomolecules

SCFMO calculations of heteroatomic systems with the variable? approximation: I. Heteroatomic molecules containing nitrogen or oxygen atoms

The transition energies and intensities of naphthalene, anthracene, phenanthrene, pyrene, and azulene are calculated with a variable β modification of the Pariser-Parr-Pople method. In this procedure each β is determined from the bond order after every iteration. The dependence of β on bond order is given by β = −0.51 p + A
0 eV where A
0 is −1.90 eV (naphthalene and azulene), −1.84 eV (anthracene and phenanthrene), and −1.82 eV (pyrene). Precise knowledge of the molecular geometry is not required and the results are in good agreement with experiment.

SCF calculations of aromatic hydrocarbons the variable β approximation

An integrating sphere has been adapted to the measurement of the quantum yield of the fluorescence of solutions of pigments. The intensities of the fluorescence and of the absorbed light were determined separately with a thermopile.Chlorophylls a and b dissolved in various solvents have been studied with this apparatus over a range of concentrations, and the measured yields corrected for autoabsorption. The yield for chlorophyll a is 0.25 and is in general independent of solvent and excitation wavelength. The yield for chlorophyll b is 0.11 for ether solutions and 0.06 for methanol solutions. The absolute fluorescent yields of solutions of fluorescein, eosine, magdala red, and rubrene were also measured. These results are in reasonable agreement with the published values of the yields for the same compounds.
