Site-directed psbA mutants at the tyrosine Y 112 position have been generated in Synechocystis PCC6803 cells. The mutation Y 112F does not affect photosystem II (PSII) activity as compared with control 4AIK cells. However, the Y112L mutant exhibits a photosynthetically impaired phenotype. PSII activ
