|
|
|
|
|
|
||
| UniProt code: Q55013. |
|
||
| Organism: | |
Synechocystis sp. (strain PCC 6803 / Kazusa). |
| Taxonomy: | |
Bacteria; Cyanobacteria; Synechococcales; Merismopediaceae; Synechocystis; unclassified Synechocystis. |
|
||
|
||
| Function: | |
Low-potential cytochrome c that plays a role in the oxygen- evolving complex of photosystem II (PSII). Required for normal function or stabilization of PSII. Extrinsic protein associated with PSII that enhances oxygen evolution. {ECO:0000305}. |

| Cofactor: | |
Name=heme; Xref=ChEBI:CHEBI:30413; Evidence={ECO:0000269|PubMed:11315568, ECO:0000269|PubMed:12069591}; Note=Binds 1 heme group covalently per subunit. {ECO:0000269|PubMed:11315568, ECO:0000269|PubMed:12069591}; |
| Subunit: | |
The cyanobacterial oxygen-evolving complex is composed of PsbO, PsbP, PsbQ, PsbV and PsbU. {ECO:0000255|HAMAP-Rule:MF_01378, ECO:0000269|PubMed:12069591}. |
| Subcellular location: | |
Cellular thylakoid membrane {ECO:0000269|PubMed:12069591, ECO:0000305}; Peripheral membrane protein {ECO:0000269|PubMed:12069591, ECO:0000305}; Lumenal side {ECO:0000305|PubMed:7896839}. Note=Associated with photosystem II at the lumenal side of the thylakoid membrane. {ECO:0000305|PubMed:7896839}. |
| Disruption phenotype: | |
Cells show decreased but not abolished level of PSII and photoautotrophic growth. {ECO:0000269|PubMed:7896839}. |
| Similarity: | |
Belongs to the cytochrome c family. PsbV subfamily. {ECO:0000255|HAMAP-Rule:MF_01378}. |
| Sequence caution: | |
Sequence=AAA19982.2; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305}; |
