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. {ECO:0000250|UniProtKB:O82660}.
CC   -!- SUBCELLULAR LOCATION: Plastid, cyanelle thylakoid lumen
CC       {ECO:0000255|HAMAP-Rule:MF_01348}. Note=Associated with a PSII precusor
CC       complex on the lumenal side of the thylakoid membrane.
CC       {ECO:0000255|HAMAP-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}.
