The Chloroplast NAD(P)H Dehydrogenase Complex Interacts with Photosystem I in Arabidopsis
Open accessAbstract
The chloroplast NAD(P)H dehydrogenase (NDH) complex is involved in photosystem I (PSI) cyclic and chlororespiratory electron transport in higher plants. Although biochemical and genetic evidence for its subunit composition has accumulated, it is not enough to explain the complexes putative activity of NAD(P)H-dependent plastoquinone reduction. We analyzed the NDH complex by using blue native PAGE and found that it interacts with PSI to form a novel supercomplex. Mutants lacking NdhL and NdhM accumulated a pigment-protein complex with a slightly lower molecular mass than that of the NDH-PSI supercomplex; this may be an intermediate supercomplex including PSI. This intermediate is unstable in mutants lacking NdhB, NdhD, or NdhF, implying that it includes some NDH subunits. Analysis of thylakoid membrane complexes using sucrose density gradient centrifugation supported the presence of the NDH-PSI supercomplex in vivo. Although the NDH complex exists as a monomer in etioplasts, it interacts with PSI to form a supercomplex within 48 h during chloroplast development.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
