the elongation factors ef-tu and ef-g interact with ribosomes during protein synthesis : ef-tu presents incoming aminoacyl transfer rna to the programmed ribosome as an ef-tu-gtp-trna ternary complex and ef-g promotes translocation of peptidyl-trna and its associated messenger rna from the a to the p site after peptidyl transfer .
