CC   -!- FUNCTION: This protein promotes the GTP-dependent binding of aminoacyl-
CC       tRNA to the A-site of ribosomes during protein biosynthesis.
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
CC   -!- SIMILARITY: Belongs to the TRAFAC class translation factor GTPase
CC       superfamily. Classic translation factor GTPase family. EF-Tu/EF-1A
CC       subfamily. {ECO:0000305}.
