Abstract: Ricardo Ferreira foi o primeiro cientista brasileiro a compreender a necessidade de aproximações teóricas sólidas para explicar os mecanismos que governam as ciências da vida. Nesta edição em sua homenagem, descrevemos como modelos teóricos têm sido aplicados para guiar o entendimento do fenômeno de tunelamento de elétrons em biologia. Durante quase vinte anos, o nosso modelo de "Pathways" tem se mostrado o mais bem sucedido modelo teórico para descrever o mecanismo de tunelamento no processo de transferência … Show more

“…The converged eigenvalues provide the energies of the poles of the non-adiabatic intersection, and at this point, the GFM elements, G ij , represent the tunneling probabilities of the electron through the atomic orbital (AO) space of the bridge states between D and A. [4][5][6][7][8]22 Larger absolute magnitudes of G ij indicate a higher probability of electronic propagation from the i-th orbital to the j-th orbital, and contribute to a more dominant orbital pathway for the tunneling electron. 4,7,8,31 Alternating numeric signs of Green's function elements along a pathway, which relate to alternating phases of the orbitals in the pathway, are indicative of constructive interference and/or dominance of this single pathway.…”

“…The ET between the redox centers mediated by peptide bridges has been thought to involve two possible mechanisms: the superexchange model and electron hopping model2526272829. In the superexchange (or tunneling) mechanism, ET takes place via coupling between the virtual states of the bridging units and involves tunneling movement through the bridge part without a transient stay in the bridge state; in such circumstances the rate constant shows an exponential decaying function of the peptide length30. This mechanism can thus be described as having the decay parameter β that is dependent on the bridge length, the conformational rigidity and the electronic properties of the electron donor and acceptor31323334.…”
