CC   -!- FUNCTION: Unknown. The ortholog in A.thaliana is involved in
CC       photosystem II (PSII) assembly, but knockout of the corresponding gene
CC       in Synechoccus PCC 7002 has no effect on PSII activity.
CC   -!- FUNCTION: A factor required for optimal assembly of photosystem II
CC       (PSII), acting in the early stages of PSII assembly. Also plays a role
CC       in replacement of photodamaged D1 (psbA). Assists YidC in synthesis of
CC       chlorophyll-binding proteins. {ECO:0000255|HAMAP-Rule:MF_01348}.
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. {ECO:0000255|HAMAP-Rule:MF_01348}.
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid lumen {ECO:0000255|HAMAP-
CC       Rule:MF_01348}. Note=Associated with a PSII precusor complex on the
CC       lumenal side of the thylakoid membrane. {ECO:0000255|HAMAP-
CC       Rule:MF_01348}.
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. {ECO:0000255|HAMAP-
CC       Rule:MF_01348}.
CC   -!- SIMILARITY: Belongs to the Ycf48 family. {ECO:0000255|HAMAP-
CC       Rule:MF_01348}.
