英文摘要Ndi1 is a special type-II complex I nicotinamide-adenine-dinucleotide (NADH): ubiquinone (UQ) oxidoreductase in the yeast respiratory chain, with two bound UQs (UQI and UQII) mediating electron transfer from flavin cofactors to ubiquinone, in the absence of Fe-S chains. Here, we elucidate the underlying mechanism of electron transfer in Ndi1 through temperature-dependent Electron Spin Resonance (ESR) experiments in conjunction with quantum chemical calculations. It is revealed that electron transfer is mediated by antiferromagnetic (AFM) interactions between flavin-adenosine-dinucleotide (FAD) and UQI and between UQI and UQII. The p-stacking interactions among the aromatic complexes also enhance the throughspace electron transfer. The FAD/UQI pair works as a rectifier converting double-electron co-transfer into sequential single-electron transfer events. The results not only expand our understanding on the observed AFM interactions among p-orbital aromatic mixed-stack in proteins, but also provide significant insights into the fabrication of materials with special magnetic properties using biological samples.
