LITERATURE
N234D
mutation of residue that interacts with two of the phosphatidylglycerol molecules of the complex. Mutant exhibits normal growth, but shows decreased photosynthetic activities and slower electron transport from QA to QB than the control strain
S232A
mutation of residue that interacts with two of the phosphatidylglycerol molecules of the complex. Mutant exhibits normal growth, but shows decreased photosynthetic activities and slower electron transport from QA to QB than the control strain
S232A/N234D
mutation of residues that interact with two of the phosphatidylglycerol molecules of the complex. Mutant exhibits normal growth, but shows decreased photosynthetic activities and slower electron transport from QA to QB than the control strain. The levels of extrinsic proteins, PsbV and PsbU, are decreased in PSII monomers, while that of Psb28 is increased. The content of phosphatidylglycerol in PSII is slightly decreased, whereas that of monogalactosyldiacylglycerol is increased
S264K
mutation in protein D1. Mutant displays a severe and persistent hampering of the QA-QB electron transfer resulting in a delay of the plastoquinone pool reduction rate
