CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid lumen
CC       {ECO:0000250|UniProtKB:O82660}.
CC   -!- DOMAIN: A 7-bladed beta-propeller torus, about 54 by 55 Angstroms, with
CC       a depth of about 25 Angstroms and a central pore.
CC       {ECO:0000250|UniProtKB:M1VJU3}.
CC   -!- SIMILARITY: Belongs to the Ycf48 family. {ECO:0000305}.
