Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
For reconstitution add 50 µL of sterile water.

Cyt f is the c-type cytochrome subunit of the photosynthetic cytochrome b6f complex, encoded by the chloroplast petA gene and integrated into the thylakoid membrane with a single C-terminal transmembrane helix that anchors a large hydrophilic domain on the lumenal side. The mature protein binds a high-potential c-type heme via the canonical Cys-X2-Cys-His motif, forming a predominantly beta-sheet-rich extrinsic (lumen-facing) domain with an unusual heme iron axial ligation involving the N-terminus, as revealed by X-ray crystallography. Functionally, Cyt f accepts electrons from the Rieske 2Fe-2S protein within cytochrome b6f and donates them to plastocyanin in the thylakoid lumen, thereby supporting intersystem electron transfer between photosystem II and photosystem I; this process is coupled, at the complex level, to proton translocation that contributes to the proton motive force driving ATP synthesis.
