Protein
Cytochrome b6-f complex subunit 6
Organism
Nostoc sp. (strain PCC 7120 / SAG 25.82 / UTEX 2576)
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. PetL is important for photoautotrophic growth as well as for electron transfer efficiency and stability of the cytochrome b6-f complex.
Similarity
Belongs to the PetL family.
