Protein

Photosystem I reaction center subunit III, chloroplastic

Gene

PSAF

Organism
Spinacia oleracea (Spinach)
Status
Reviewed - Annotation score: 3 out of 5- 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.
