Abstract
The chloroplast NADH dehydrogenase-like complex (NDH) was first discovered based on its similarity to complex I in respiratory electron transport. However, it seems to be a ferredoxin-dependent plastoquinone reductase rather than an NAD(P)H dehydrogenase. Furthermore, it also comprises a subcomplex on the stromal side of the thylakoid membrane and a lumenal subcomplex [ 1 ]. The chloroplast NDH complex has been divided into four categories: membrane, lumen, A, and B subcomplexes. The subcomplex A and membrane subcomplex are conserved in cyanobacteria, but the subcomplex B and lumen subcomplex are specific to chloroplasts. PNSB4/NDF6 is a subunit of subcomplex B [ 2 ].
