CC -!- FUNCTION: IF-3 binds to the 30S ribosomal subunit and shifts the
CC equilibrum between 70S ribosomes and their 50S and 30S subunits in
CC favor of the free subunits, thus enhancing the availability of 30S
CC subunits on which protein synthesis initiation begins.
CC {ECO:0000255|HAMAP-Rule:MF_00080}.
CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_00080}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00080}.
CC -!- SIMILARITY: Belongs to the IF-3 family. {ECO:0000255|HAMAP-
CC Rule:MF_00080}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAY91387.2; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
