Protein Family Models

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 [1]. 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 [1]. [1]. 7493961.

Cytochrome b6-f complex subunit 5; plastohydroquinone/plastocyanin oxidoreductase; with PetL, PetM and PetN makes up the small subunit of the cytochrome b6-f complex; cytochrome b6-f mediates electron transfer between photosystem II and photosystem I

cytochrome b6-f complex subunit PetG is a component of the cytochrome b6-f complex, which mediates electron transfer between photosystem II (PSII) and photosystem I (PSI), cyclic electron flow around PSI, and state transitions
