The two forms of the S2 state multiline signal in photosystem 11: Effect of methanol and ethanol

Ahrling, Karin; Evans, M C W; Nugent, J H A; Pace, Ronald


The characteristic Mn hyperfine 'multiline' signal exhibited in the S 2 state of the oxygen-evolving complex (OEC) complex of Photosystem II (PSII) has been shown to be heterogeneous in character. In this study, we have explored the effects that influence the proportions of the two forms of the S2 state multiline signal present in any sample. The narrow form of the signal is lost upon storage (weeks) at 77 K, whereas the broad form remains. In particular, we explore the roles of ethanol and...[Show more]
