Protein

Cytochrome c-550

Gene

psbV

Organism
Thermosynechococcus elongatus (strain BP-1)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Low-potential cytochrome c that plays a role in the oxygen-evolving complex of photosystem II. It is not essential for growth under normal conditions but is required under low CO2 concentrations. PSII is a light-driven water plastoquinone oxidoreductase, using light energy to abstract electrons from H2O, generating a proton gradient subsequently used for ATP formation.4 Publications

Cofactori

Note: Binds 1 heme group covalently per subunit. PSII binds multiple chlorophylls, carotenoids and specific lipids.12 Publications

Interactioni

Subunit structurei

The cyanobacterial oxygen-evolving complex is composed of PsbO, PsbP, PsbQ, PsbV and PsbU (By similarity). PsbP and PsbQ are not seen in the crystal structures; however there is biochemical evidence that they are part of the OEC. Monomer in the isolated crystal structure. Cyanobacterial PSII is composed of 1 copy each of membrane proteins PsbA, PsbB, PsbC, PsbD, PsbE, PsbF, PsbH, PsbI, PsbJ, PsbK, PsbL, PsbM, PsbT, PsbX, PsbY, PsbZ, Ycf12, 3 peripheral proteins PsbO, PsbU, PsbV and a large number of cofactors. It forms dimeric complexes.UniRule annotation10 Publications

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
