CC   -!- FUNCTION: Responsible for the release of ribosomes from messenger RNA
CC       at the termination of protein biosynthesis. May increase the efficiency
CC       of translation by recycling ribosomes from one round of translation to
CC       another. {ECO:0000255|HAMAP-Rule:MF_00040}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00040}.
CC   -!- SIMILARITY: Belongs to the RRF family. {ECO:0000255|HAMAP-
CC       Rule:MF_00040}.
