Proteins tunneling pathway model

The pathway model makes a number of key predictions, including (a) a substantial role for hydrogen bond mediation of tunnelling, (b) a difference in mediation characteristics as a function of secondary and tertiary stmcture, (c) an intrinsically nonexponential decay of rate witlr distance, and (d) patlrway specific Trot and cold spots for electron transfer. These predictions have been tested extensively. The most systematic and critical tests are provided witlr mtlrenium-modified proteins, where a syntlretic ET active group cair be attached to the protein aird tire rate of ET via a specific medium stmcture cair be probed (figure C3.2.5). [Pg.2978]

Pathways [2, 50] is a semiempirical model which it is designed to reproduce electron transfer rates between cofactors in proteins [50, 151 ]. In essence. Pathways includes the contributions to the electronic tunneling from a stepwise path covering aU non-bonded interactions, as well as the bonded ones at the nearest neighbor level. Namely ... [Pg.120]
