Abstract

Time-resolved fluorescence and fluorescence anisotropy experiments in combination with molecular dynamics simulations show that the flavin chromophore bound in oxidized and reduced flavodoxins is immobilized within the protein matrix. Experimental results show that a small fraction of the flavin chromophores in oxidized flavodoxin have more rotational freedom, as indicated by significantly smaller rotational correlation times than expected for the whole protein.
