Protein-synthesizing GTPases (EC 3.6.5.3, elongation factor (EF), initiation factor (IF), peptide-release or termination factor) are enzymes involved in mRNA translation into protein by the ribosome, with systematic name GTP phosphohydrolase (mRNA-translation-assisting).[1][2][3][4][5] They usually include translation initiation factors such as IF-2 and translation elongation factors such as EF-Tu.
