Also plays a role CC in replacement of photodamaged D1 (psbA). Assists YidC in synthesis of CC chlorophyll-binding proteins. end case case CC -!- SUBUNIT: Part of early PSII assembly complexes which includes D1 (psbA) CC and PsbI; not found in mature PSII. Binds to the periplasmic side of CC PSII complexes. Interacts with YidC. CC -!- SUBCELLULAR LOCATION: Cell inner membrane; Lipid-anchor; Periplasmic CC side. Note=Associated with a PSII precusor complex on the periplasmic CC side of the cell inner membrane. else case and CC -!- SUBUNIT: Part of early PSII assembly complexes which includes D1 (psbA) CC and PsbI; not found in mature PSII. Binds to the lumenal side of PSII CC complexes. Interacts with YidC. CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane; Lipid-anchor; CC Lumenal side. Note=Associated with a PSII precusor complex on the CC lumenal side of the thylakoid membrane. else CC -!- SUBCELLULAR LOCATION: Cellular thylakoid lumen. Note=Associated with a CC PSII precusor complex on the lumenal side of the thylakoid membrane. end case case CC -!- FUNCTION: Essential for photosystem II (PSII) biogenesis; required for CC assembly of an early intermediate in PSII assembly that includes D2 CC (psbD) and cytochrome b559. CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid lumen. end case CC -!- DOMAIN: A 7-bladed beta-propeller torus, about 55 by 55 Angstroms, with CC a depth of about 25 Angstroms and a central pore. CC -!- SIMILARITY: Belongs to the Ycf48 family.
