Elongation factor - GTP-dependent proteins that help bring aa-tRNA to the acceptor site of a ribosome during translation. Elongation factors also help in the translocation process. Energy is supplied by the hydrolysis of GTP to GDP.

EF Elongation factor; elongation factors are proteins facilitating translational elongation.

During translation elongation, tRNA first binds to the ribosome as part of a complex with elongation factor Tu (EF-Tu) or its eukaryotic (eEF-1) or archaeal counterpart. This initial tRNA binding site is called the A/T site.
The aminoacyl-tRNA is brought to the ribosome through a series of interactions with EF-Tu (an elongation factor).
During codon recognition, an elongation factor assists hydrogen bonding between the mRNA codon under the A site with the corresponding anticodon of tRNA carrying the appropriate amino acid.
This step requires the hydrolysis of two GTP.
