Extended Data Fig. 6: Sequence alignment of the positively charged amino acids and the hydrophobic surface of the PSI plastocyanin binding region.
From: The structure of a triple complex of plant photosystem I with ferredoxin and plastocyanin
The organisms used to determine amino acid alignment were Pisum sativum, Thermosynechococcus elongatus, Synechocystis sp. PCC 6803, Chlamydomonas reinhardtii, Cyanidioschyzon merolae, Euglena gracilis and Phaeodactylum tricornutum. The relevant amino acids are marked with a dark-blue rectangle. The aligned sequences were obtained using BLAST47 or the E. gracilis whole-genome shotgun contigs sequences. a, PsaA Asn641, Arg654, Asp655, Trp658, Ala659, Ser662, Gln663 and Gln666. b, PsaB Asn605, Arg621, Asp622, Trp625, Leu626, Asn627, Ser629, Gln630, Asn633 and Phe638. c, PsaA and PsaB pseudo-symmetrical luminal plastocyanin binding surface. d, PsaF Lys93, Lys96, Lys100 and Lys101. e, PsaF alignment in selected eukaryotes.
