Protein

Photosystem I reaction center subunit III

Gene

psaF

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

Functioni

Probably participates in efficiency of electron transfer from plastocyanin to P700 (or cytochrome c553 in algae and cyanobacteria). This plastocyanin-docking protein contributes to the specific association of plastocyanin to PSI (By similarity).By similarity
