| Description
| - Role phosphatidylglycerolu (PG) ve fotosyntetických membránách sinic jsme studovali v mutantu sinice Synechocystis sp. PCC6803 s chybějícími fykobilisomy a s inaktivovaným genem cdsA kódujícím cytidine 5'-diphosphate diacylglycerol synthasu, klíčový enzym biosyntézy PG. PAL/Delta cdsA mutant rostl fotoautototrofně v médiu s dodaným PG, ale odstranění PG vedlo k: (a) zastavení růstu a dělení buněk, (b) k zpomalení elektronového transportu mezi akceptory QA a QB ve fotosystému II (PSII) a (c) modifikaci chlorofylových fluorescenčních křivek. Dvourozměrná elektroforéza ukázala, že absence PG vede (a) k rozpadu dimerní formy PSII na monomery, a (b) k odtržení CP43 od zbylé části komplexu PSII (cs)
- To analyze the role of phosphatidylglycerol (PG) in photosynthetic membranes of cyanobacteria we used two mutants of Synechocystis sp. PCC6803: the PAL mutant which has no phycobilisomes and shows a high PSII/PSI ratio, and a mutant derived from it by inactivating its cdsA gene encoding cytidine 5'-diphosphate diacylglycerol synthase, a key enzyme in PG synthesis. In a medium supplemented with PG the PAL/Delta cdsA mutant cells grew photoautotrophically. Depletion of PG in the medium resulted (a) in an arrest of cell growth and division, (b) in a slowdown of electron transfer from the acceptor Q(A) to Q(B) in PSII and (c) in a modification of chlorophyll fluorescence curve. The depletion of PG affected neither the redox levels of QA nor the S-2 state of the oxygen-evolving manganese complex, as indicated by thermoluminescence studies. Two-dimensional PAGE showed that in the absence of PG (a) the PSII dimer was decomposed into monomers, and (b) the CP43 protein was detached from a major Part of th
