| UniProt code: P83795. |
|

| 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 (PubMed:14526088). PetL is important for photoautotrophic growth as well as for electron transfer efficiency and stability of the cytochrome b6-f complex. {ECO:0000305|PubMed:14526088}. |
|
||
| Subunit: | |
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. {ECO:0000269|PubMed:14526088}. |
| Subcellular location: | |
Cellular thylakoid membrane {ECO:0000305|PubMed:14526088}; Single-pass membrane protein {ECO:0000269|PubMed:14526088}. |
| Similarity: | |
Belongs to the PetL family. {ECO:0000255|HAMAP- Rule:MF_00433}. |
