elongation factor (EF)

one of a group of special proteins required for the elongation process in TRANSLATION.

elongation

1. in protein synthesis, cyclic process of growth of a polypeptide chain from mRNA attached to ribosomes. Requires mRNA, ribosomes, activated aminoacyl-tRNA, elongation factor EF-Tu activated with GTP.
2. in fatty acids, a process of adding carbon from acetyl CoA to a lengthening acyl chain. Mechanism for achieving diversity of fatty acids in biological systems.

elongation factor
one in a group of proteins involved in the elongation of polypeptide chains during protein synthesis.
