Photosystem I core complexes were isolated from spinach photosystem I particles after heat treatment in the presence of 50% ( vv) ethylene glycol (heat/EG treatment). The core complex from 58°C/EG-treated particles was composed of polypeptides with apparent molecular masses of 63, 60 and 5 kDA; this complex contained the iron sulfur center F xbut lacked center F Aand F B. The core complex obtained from the 70°C/EG-treated preparation lacked F xand contained a lesser amount of the 5 kDa polypeptide. The N-terminal amino acid sequence of the 5 kDa polypeptide did not correspond to the sequence derived from any possible reading frame in the chloroplast DNA of liverwort or tobacco. Twelve of the first 29 N-terminal amino acids were hydrophobic, suggesting that this protein is intrinsic to the photosystem I reaction center. |
