| Abstract/Contents: | "Pigments and thylakoid membrane proteins were investigated in wild type and PS I- mutants form Synechocystis sp. PCC6803. Comparing morphological features, B2 was less fluorescent than the other strains. The contents of chlorophyll a were propotional to the Fnr activity in thylakoid membrane. The FNR activity of mutants was lower than that of wild type. The major carotenoid was found to be β-caroene, but zeaxanthim was barely detected in thylakoid membrane of mutants. The polypeptide, 14.8kD was zeaxanthim was detected by electrophoresis in mutants. It was considered to be the modification of 15.4kD in wild type. Membrane polypeptides of 17.6 and 19.7kD were not detected in mutants. In the result of western blotting, subunit I was detected in all strains, but subunit II was barely detected in mutants. Subunit II was not detected in B2 at all. In view of the results so far achieved, the changes of contents of chlorophyll and zeaxanthin were affected by the defficiency or modification of functional domain in subunit I. Also the modification in subunit II binding site in PS I. As the result, efficiency of photosynthesis was decreased. |
