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.
应用类型
Immunoprecipitation (IP), Western blot (WB)
免疫原
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).
Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
