Comments [?]

Function Stabilizes the structure of photosystem II oxygen-evolving complex (OEC), the ion environment of oxygen evolution and protects the OEC against heat-induced inactivation.
Subunit With PsbO,P,Q and V forms the oxygen-evolving complex of photosystem II.
Subcellular location Cellular thylakoid membrane; Peripheral membrane protein; Lumenal side. Note=Associated with photosystem II at the Lumenal side of the thylakoid membrane.
Similarity Belongs to the PsbU family.

Comments GLOVI is very divergent, and hence atypical. For a review on the composition of the oxygen-evolving complex see: PubMed=17200881; DOI=10.1007/s11120-006-9117-1; Roose J.L., Wegener K.M., Pakrasi H.B.; "The extrinsic proteins of Photosystem II."; Photosyn. Res. 92:369-387(2007).
