General annotation (Comments)

Function

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. PetG is required for either the stability or assembly of the cytochrome b6-f complex By similarity. HAMAP-Rule MF_00432

Subunit structure

The 4 large subunits of the cytochrome b6-f complex are cytochrome b6, subunit IV (17 kDa polypeptide, PetD), cytochrome f and the Rieske protein, while the 4 small subunits are PetG, PetL, PetM and PetN. The complex functions as a dimer By similarity.

Subcellular location

Plastidchloroplast thylakoid membrane; Single-pass membrane protein By similarity HAMAP-Rule MF_00432.

Sequence similarities

Belongs to the PetG family.
