Investigation of electrochromic band-shifts in the Soret region induced by the formation of TyrD*, TyrZ*, and QA*- in Photosystem II
Alain Boussac, Takumi Noguchi, Alfred William Rutherford, Julien Sellés, Miwa Sugiura, Stefania Viola
The paper investigates the effects of TyrD*, TyrZ*, and QA*- radical formation on the Soret region absorption spectra in Photosystem II from multiple species and mutants, identifying PD1 as the blue-shifted species and suggesting other pigments may contribute to shifts from TyrD* and TyrZ*.
