title: Spectral properties of fluorescent flavoproteins of isolated rat liver mitochondria.
abstract: The different flavoproteins contributing to flavin fluorescence of isolated rat liver mitochondria have distinct excitation and emission spectra. The NAD-linked flavin component was identified as alpha-lipoamide dehydrogenase, while the non-NAD-linked component was found to be electron transfer flavoprotein. The differences in excitation and emission properties of the mitochondrial flavoproteins permit selective recording of their redox state changes in isolated mitochondria.
