PNSL2

Gene
PNSL2
Protein
Photosynthetic NDH subunit of lumenal location 2, chloroplastic
Organism
Arabidopsis thaliana
Length
190 amino acids
Function
NDH shuttles electrons from NAD(P)H:plastoquinone, via FMN and iron-sulfur (Fe-S) centers, to quinones in the photosynthetic chain and possibly in a chloroplast respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be plastoquinone. Couples the redox reaction to proton translocation, and thus conserves the redox energy in a proton gradient (Probable). Required for both formation and activity of the chloroplast NAD(P)H dehydrogenase (NDH) complex (PubMed:20430763, PubMed:20460499).
Similarity
Belongs to the psbQ family.
