摘要: Abstract Reported donor–acceptor distance-dependent rates of photo-induced electron transfer from tryptophan (Trp), tyrosine (Tyr), and benzoate (Bz) to the excited isoalloxazine in ten flavoprotein systems were analyzed with three kinds theories by Marcus, Bixon Jortner, also Kakitani, Yoshimori, Mataga. Average distances that obtained X-ray structures flavoproteins used for analysis, rather than edge-to-edge distance. The observed best reproduced Mataga theory.
