“…The strong resemblance between the fluorescence spectra of Figs. 1 and 2 and those of amino acid derivatives, such as modified tryptophans (Finazzi-Agro & Avigliano, 1984), pyridinoline (Tshuchikura et al, 1981) and functional cofactors, such as quinones (Anthony & Zatman, 1967;Duine et al, 1987) and folates (Uyeda & Rabinowitz, 1963), does not resolve the assignment. Thus it is necessary to employ chemical methods to identify the fluorophore.…”

The origin of the 440 nm fluorescence of horse spleen ferritin and of Pseudomonas aeruginosa and Azotobacter vinelandii bacterioferritin has been investigated using a Nitro Blue Tetrazolium/glycinate colorimetric test specific for quinones [Paz, Fliickiger, Boak, Kagan & Gallop (1991) J. Biol. Chem. 266, 689-692]. The results of the analysis indicate that ferritin and bacterioferritins contain quinones. A possible functional role of these quinones in iron uptake and release is described, as is the possibility that the presence of quinones in these proteins results from oxidative damage.
