product information

Multi-subunit complex of cytb6/f is a crucial component for the photosynthetic electron transport chain of higher plants, green algae and cyanobacteria. This complex is catalyzing oxidation of quinols and the reduction the reduction of plastocyanin. This reaction allows to establish the proton force required for the ATP synthesis. Four major subunits build the complex: the petA gene product corresponding to a c-type cytochrome (cytf), the petB gene product corresponding to a b-type/c’-type cytochrome with three haems (cyt b6), the petD gene product (subunit IV, or suIV), and the petC gene product, corresponding to the Rieske/Iron/sulfur protein.

application example


Chlamydomonas reinhardtii samples are lysed cells, Arabidopsis thaliana samples are prepared from thylakoid membranes; Samples were boiled 1 min in 3%SDS,then 10ug of chlorophylls were loaded in each well of a 12% acrylamide gel.
