This entry includes protein from blue-green algae and plants, including CRR7 (Chlororespiratory reduction 7) protein from Arabidopsis. CRR7 is part of the chloroplastic NAD(P)H dehydrogenase complex (NDH Complex) involved in respiration, photosystem I (PSI) cyclic electron transport and CO2 uptake [ 1 ]. It is essential for the stable formation of the NDH Complex [ 2 ].
