Biochemical properties

Eukaryotic elongation factor 1 (EF-1) is responsible for the GTP-dependent binding of aminoacyl-tRNAs to the ribosomes. It is composed of four subunits. The β and δ chains are highly similar proteins that both stimulate the exchange of GDP bound to the α chain for GTP [1]. On their N-termini, they contain a domain similar to the C-terminal domain of glutathione S-transferase (AllFam:AF010).

Allergens from this family

Pen c 24, a minor allergen from Penicillium citrinum was identified as EF-1β [2].
