Fig. 3: Flash-number dependence of the IR difference absorption of PSII core complexes from Synechocystis sp. PCC 6803.

Data of wild-type PSII (blue), as well as PSII with point mutations D61A (green) and N298A (red) of the D1 protein subunit is shown for a 1384 cm−1, b 1400 cm−1, c 1514 cm−1, and d 1544 cm−1. Each data point was obtained by averaging the IR difference absorption between 700 and 800 ms following the nth excitation flash (n = 1,…, 10). The exciting laser flashes were spaced by 1 s.
