[Unity of the polypeptides compound from the pigment-protein complex of photosystem I and the auxiliary chlorophyll-a/b-containing complex in higher plant chloroplasts].
The polypeptide compositions of the light-harvesting chlorophyll a/b-protein complex (LHC) and of the complex of photosystem I (CP I) denatured with 2% beta-mercaptoethanol and 8 M urea was investigated. The LHC complex consists of two major (23 and 21 KD) and two minor (19 and 15 KD) polypeptides; the CP I complex consists of one major (23 KD) and three minor (19, 16 and 14 KD) proteins. The 70 KD protein which was considered to be characteristic for CP I is most likely an oligomer made up of three subunits (23 KD) and other minor protein components.
