Protein
Photosystem II reaction center X protein
Organism
Thermosynechococcus elongatus (strain BP-1)
Function
Involved in the binding and/or turnover of quinones at the Q(B) site of Photosystem II. PSII is a light-driven water plastoquinone oxidoreductase, using light energy to abstract electrons from H(2)O, generating a proton gradient subsequently used for ATP formation.
Similarity
Belongs to the PsbX family. Type 1 subfamily.
