Function |
NDH-1 shuttles electrons from NAD(P)H, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be plastoquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient. |

Comments |
In dicots the initiation codon seems to be created by RNA editing (has been proven for TOBAC, ARATH, SPIOL, OENEH and snapdragon). |
