Cytochrome b6-f complex subunit 6

Gene

petL

Organism
Mastigocladus laminosus (Fischerella sp.)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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 (PubMed:14526088). PetL is important for photoautotrophic growth as well as for electron transfer efficiency and stability of the cytochrome b6-f complex.1 Publication

Subunit structurei

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.1 Publication
