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 system name GTP phosphohydrolase (mRNA-translation-assisting). They usually include translation initiation factors such as IF-2 and translation elongation factors such as EF-Tu.
