TL;DR: A strong electrochromic shift at 685 nm in the final P700+A1− spectrum that can only be explained if Chl a is in the positions Chl2A/Chl2B, hence, Chl f is likely to function solely as an antenna pigment in FRL-PSI.

Evidence that histidine forms a coordination bond to the A0A and A0B chlorophylls and a second H-bond to the A1A and A1B phylloquinones in M688HPsaA and M668HPsaB variants of Synechocystis sp. PCC 6803

TL;DR: The axial ligands of the acceptor chlorophylls in Photosystem I are the Met sulfur atoms of M688 (PsaA) and M668(PsaB), and to determine the role of the Met, His variants were generated in Synechocystis sp.

TL;DR: Yaroshevich et al. as discussed by the authors proposed a possible photoactivation mechanism of a 35-kDa blue light-triggered photoreceptor, the Orange Carotenoid Protein (OCP), suggesting that the reaction involves the transient formation of a protonated ketocarotinoid (oxocarbenium cation) state.

TL;DR: In this paper, the role of the accessory chlorophyll (Chl) molecules, Chl2A and Chl 2B, was identified by ultrafast pump-probe spectroscopy in three pairs of photosystem I complexes from Synechocystis sp. PCC 6803 with residues PsaA-N600 or PsaB-N582 substituted by Met, His, and Leu.
