[7] The elongation phase of translation is promoted by three universal elongation factors, EF-Tu, EF-Ts, and EF-G.[9] EF-P was discovered in 1975 by Glick and Ganoza,[10] as a factor that increased the yield of peptide bond formation between initiator fMet-tRNA(fMet) and a mimic of aa-tRNA, puromycin (Pmn). Alkalaeva EZ, Pisarev AV, Frolova LY, Kisselev LL, Pestova TV. Biochim Biophys Acta Gene Regul Mech. [9] EF-P consists of three -barrel domains (I,II and III) and has a L shape tRNA structure. They assist in elongating the nascent polypeptide chain by one amino acid at a time. Recent discoveries of elongation factor-related proteins have considerably complicated the simple textbook scheme of the peptide chain elongation cycle.
