摘要：

In a previous study we found that the 33 kDa extrinsic polypeptide of Photosystem II is present in both the cytoplasmic and thylakoid membranes of cyanobacteria, but forms part of a functional complex only in the latter [Smith et al. (1987) Mol. Microbiol. 6, 1821-1827]. In order to determine if this phenomenon is restricted to the 33 kDa polypeptide we have extended this study in Anacystis nidulans to include a number of other polypeptides of Photosystem I and Photosystem II. We have found that Dl and possibly PsaC are present in both membranes, CP43 and CP47 are confined to the thylakoid membranes, and the distribution of PsaD and PsaE is dependent upon the growth stage of the cyanobacteria.
