The time-resolved fluorescence and fluorescence anisotropy characteristics of reduced flavin mononucleotide in solution as well as bound in flavodoxins isolated from the bacteria Desulfovibrio gigas, Desulfovibrio vulgaris, Clostridium beijerinckii MP and Megasphaera elsdenii have been examined. All fluorescence and fluorescence anisotropy decays were(More)
The time-resolved fluorescence characteristics of tryptophan in flavodoxins isolated from the bacteriaDesulfovibrio gigas, Desulfovibrio vulgaris, Clostridium beijerinckii, andMegasphaera elsdenii were examined. The fluorescence decays were recorded using pulsed synchrotron radiation as the excitation source and time-correlated single-photon counting in(More)
The time-resolved fluorescence characteristics of flavin in oxidized flavodoxin isolated from the anaerobic bacterium Clostridium beijerinckii have been examined. The fluorescence intensity decays were analyzed using the maximum-entropy method. It is demonstrated that there exist large differences in fluorescence behaviour between free and protein-bound(More)
Molecular dynamics simulations of oxidized and reduced Clostridium beijerinckii flavodoxin in water have been performed in a sphere of 1.4-nm radius surrounded by a restrained shell of 0.8 nm. The flavin binding site, comprising the active site of the flavodoxin, was in the center of the sphere. No explicit information about protein-bound water molecules(More)
