摘要
Significance The role of the electron spin in chemistry and biology has been receiving much attention because of a plausible relation to electromagnetic field effects on living organisms. Part of the difficulty in studying the subject arises from the lack of a physical model that can rationalize these phenomena. Recently the chiral-induced spin selectivity effect was observed in electron transmission through organic molecules. The question is to what extent the effect takes place in proteins. In the present study, we probed bacteriorhodopsin embedded in its native membrane environment. We observed clear evidence for spin-dependent electron transmission through this system. The results point to the possibility that the effect may play a role in electron transfer in biological systems.
