CC   -!- FUNCTION: Seems to be required for maximal rate of protein
CC       biosynthesis. Enhances ribosome dissociation into subunits and
CC       stabilizes the binding of the initiator Met-tRNA(I) to 40 S ribosomal
CC       subunits. {ECO:0000255|HAMAP-Rule:MF_00216}.
CC   -!- SIMILARITY: Belongs to the eIF-1A family. {ECO:0000255|HAMAP-
CC       Rule:MF_00216}.
