Description | Photosystem I (PSI) [ ] is an integral membrane protein complex that uses light energy to mediate electron transfer from plastocyanin to ferredoxin. It is found in the chloroplasts of plants and cyanobacteria. PSI is composed of at least 14 different subunits, two of which are small hydrophobic proteins of about 7 to 9 Kd and evolutionary related, PsaG (also known as PSI-G) and PsaK (also known as PSI-K), both integral membrane proteins. Cyanobacteria contain only PsaK []. While cyanobacterial PSI have phycobilisomes to harvest light, eukaryotic PSI have a membrane-imbedded peripheral antenna []. This entry represents Photosystem I reaction center subunit psaK found in plants, predominantly in Streptophytes. PsaK is important for stable interaction and proper function of the antenna [ ]. The crystal structure of the plant PSI complex show this protein is closely related to the similar subunit PsaG []. |
