Elongation factors are a set of proteins that bring new t-RNA to the A-site and the movement of the t-RNA from A-site to p-site.
Types of Elongation factors
EF- Tu: Binds GTP; brings aminoacyl- tRNA to the A site of ribosome
EF- Ts: Generates active EF- Tu
EF- G: Stimulates translocation; GTP- dependent
