PsaD (PSI-D) is a core subunit of photosystem I highly conserved in all photosynthetic organisms (including bacteria with Fe-S type reaction centers). In eukaryots its encoded by 1 to 2 nuclear gene(s) and imported as a precursor into the chloroplast. In the thylakoid membrane it associates with PsaA and PsaB on the stromal site of the PSI core forming the Fd-docking site. PsaD is also required for the stable assembly of PsaC.

KLH-conjugated synthetic peptide 100% conserved in all known plant PsaD sequences including Arabidopsis thaliana PSI-D1 UniProt:Q9S7H1 , TAIR: At4g02770 and PSI-D2 UniProt: Q9SA56 , TAIR At1g03130 as well as Physcomitrella patens. The conservation in Chlamydomonas reinhardtii is high (14 of 16 aminoacids are identical).
