Comments [?]

case <OC:Cyanobacteriota>
Function A factor required for optimal assembly of photosystem II (PSII), acting in the early stages of PSII assembly. Also plays a role in replacement of photodamaged D1 (psbA). Assists YidC in synthesis of chlorophyll-binding proteins.
end case
case <OC:Gloeobacter>
Subunit Part of early PSII assembly complexes which includes D1 (psbA) and PsbI; not found in mature PSII. Binds to the periplasmic side of PSII complexes. Interacts with YidC.
Subcellular location Cell inner membrane; Lipid-anchor; Periplasmic side. Note=Associated with a PSII precusor complex on the periplasmic side of the cell inner membrane.
else case <OC:Cyanobacteriota> and <Feature:PS51257>
Subunit Part of early PSII assembly complexes which includes D1 (psbA) and PsbI; not found in mature PSII. Binds to the lumenal side of PSII complexes. Interacts with YidC.
Subcellular location Cellular thylakoid membrane; Lipid-anchor; Lumenal side. Note=Associated with a PSII precusor complex on the lumenal side of the thylakoid membrane.
else
Subcellular location Cellular thylakoid lumen. Note=Associated with a PSII precusor complex on the lumenal side of the thylakoid membrane.
end case
case <OG:Chloroplast>
Function Essential for photosystem II (PSII) biogenesis; required for assembly of an early intermediate in PSII assembly that includes D2 (psbD) and cytochrome b559.
Subcellular location Plastid, chloroplast thylakoid lumen.
end case
Domain A 7-bladed beta-propeller torus, about 55 by 55 Angstroms, with a depth of about 25 Angstroms and a central pore.
Similarity Belongs to the Ycf48 family.
