Cytochrome B6-F complex subunit 5 This family consists of cytochrome B6-F complex subunit 5 (PetG). The cytochrome bf complex found in green plants, eukaryotic algae and cyanobacteria, connects photosystem I to photosystem II in the electron transport chain, functioning as a plastoquinol:plastocyanin/cytochrome c6 oxidoreductase. PetG or subunit 5 is associated with the bf complex and the absence of PetG affects either the assembly or stability of the cytochrome bf complex in Chlamydomonas reinhardtii. |
