R PF08802 CytB6-F_Fe-S Cytochrome B6-F complex Fe-S subunit Domain The cytochrome B6-F complex mediates electron transfer between photosystem II (PSII) and photosystem I (PSI), cyclic electron flow around PSI, and state transitions. This domain corresponds to the alpha helical transmembrane domain of the cytochrome B6-F complex iron-sulphur subunit. PFAM PF08802

C PF00355 Rieske Rieske [2Fe-2S] domain Domain The rieske domain has a [2Fe-2S] centre. Two conserved cysteines coordinate one Fe ion, while the other Fe ion is coordinated by two conserved histidines. In hyperthermophilic archaea there is a SKTPCX(2-3)C motif at the C-terminus. The cysteines in this motif form a disulphide bridge, which stabilises the protein [4]. PFAM PF00355
