Function
NDH (NADH dehydrogenase) functions as an electron shuttle, transferring electrons from NAD(P)H to plastoquinone. This process utilizes flavin mononucleotide (FMN) and iron-sulfur (Fe-S) clusters as intermediate electron carriers within the photosynthetic electron transport chain, and potentially also within a chloroplast respiratory chain. In this organism, plastoquinone is considered the primary electron acceptor for NDH. The enzyme couples this redox reaction to proton translocation, thereby conserving the redox energy as a proton gradient.
