OX NCBI_TaxID=176551; RN [1] RP NUCLEOTIDE SEQUENCE. RA Panero J.L., Baldwin B.G., Schilling E.E., Clevinger J.A.; RL Submitted (JAN-2003) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: NDH shuttles electrons from NAD(P)H:plastoquinone, via CC FMN and iron-sulfur (Fe-S) centers, to quinones in the CC photosynthetic chain and possibly in a chloroplast respiratory CC chain. The immediate electron acceptor for the enzyme in this CC species is believed to be plastoquinone. Couples the redox CC reaction to proton translocation, and thus conserves the redox CC energy in a proton gradient (By similarity). CC -!- CATALYTIC ACTIVITY: NAD(P)H + plastoquinone = NAD(P)(+) + CC plastoquinol. CC -!- COFACTOR: Binds 2 4Fe-4S clusters per subunit (By similarity). CC -!- SUBUNIT: NDH is composed of at least 16 different subunits, 5 of CC which are encoded in the nucleus (By similarity). CC -!- SUBCELLULAR LOCATION: Plastid; chloroplast; chloroplast thylakoid CC membrane; peripheral membrane protein (By similarity).
