Specific requirements for cytochrome c-550 and the manganese-stabilizing protein in photoautotrophic strains of Synechocystis sp. PCC 6803 with mutations in the domain Gly-351 to Thr-436 of the chlorophyll-binding protein CP47.


The requirement of cytochrome c-550 (PSII-V) in photosystem II (PSII) has been assessed in Synechocystis sp. PCC 6803 containing mutations between Gly-351 and Thr-436 of the loop E domain of the chlorophyll a-binding protein CP47. Six photoautotrophic strains were utilized to compare the effect of removal of either the manganese-stabilizing protein (PSII-O… (More)
