Structural basis for electron transport mechanism of complex I-like photosynthetic NAD(P)H dehydrogenase

Abstract

NAD(P)H dehydrogenase-like complex NDH-1L couples the electron transport from ferredoxin (Fd) to plastoquinone (PQ) and proton pumping from cytoplasm to the lumen. Here authors report two structures of NDH-1L from Thermosynechococcus elongatus BP-1, in complex with one Fd and an endogenous PQ, respectively.
