Comments [?]

Function Involved in the binding and/or turnover of quinones at the Q(B) site of Photosystem II.
Subunit PSII consists of a core antenna complex that captures photons, and an electron transfer chain that converts photonic excitation into a charge separation. PSII forms dimeric complexes.
Subcellular location Cellular thylakoid membrane; Single-pass membrane protein.
Similarity Belongs to the PsbX family. Type 2 subfamily.
