CC -!- FUNCTION: Increases the formation of ribosomal termination complexes
CC and stimulates activities of RF-1 and RF-2. It binds guanine
CC nucleotides and has strong preference for UGA stop codons. It may
CC interact directly with the ribosome. The stimulation of RF-1 and RF-2
CC is significantly reduced by GTP and GDP, but not by GMP.
CC {ECO:0000255|HAMAP-Rule:MF_00072}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00072}.
CC -!- SIMILARITY: Belongs to the TRAFAC class translation factor GTPase
CC superfamily. Classic translation factor GTPase family. PrfC subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_00072}.
