CC   -!- FUNCTION: Seems to be required for the assembly of the photosystem I
CC       complex. {ECO:0000255|HAMAP-Rule:MF_00437}.
CC   -!- SUBCELLULAR LOCATION: Plastid thylakoid membrane {ECO:0000305}; Multi-
CC       pass membrane protein {ECO:0000255|HAMAP-Rule:MF_00437}.
CC   -!- SIMILARITY: Belongs to the Ycf4 family. {ECO:0000255|HAMAP-
CC       Rule:MF_00437}.
CC   -!- CAUTION: Only inflorescences, fruits, starved seedlings and stressed
CC       stem tips are green in this organism. {ECO:0000305}.
