Class of enzymes
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 .
