Protein

Photosystem II reaction center protein T

Gene

psbT

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

Functioni

Seems to play a role in the dimerization of PSII. 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.UniRule annotation4 Publications

Cofactori

Note: PSII binds multiple chlorophylls, carotenoids and specific lipids.11 Publications

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.
