Photosensitized electron transfer are studied in three systems: lysozyme, its inhibitors (oligosaccharides) and their enzyme-inhibitor complexes. Electron donors were either tryptophane amino acid residues of lysozyme or tryptophane. It is shown that N-acetyl group of inhibitor molecules is a single electron--acceptor group in the inhibitor molecule as well as in the lysozyme-inhibitor complex. It is stated that the localization of unpaired electrons in the mixtures of lysozyme modification products and substrate--inhibitors depends on the state of enzyme molecule.
