Function

[EFG_THET8] Catalyzes the GTP-dependent ribosomal translocation step during translation elongation. During this step, the ribosome changes from the pre-translocational (PRE) to the post-translocational (POST) state as the newly formed A-site-bound peptidyl-tRNA and P-site-bound deacylated tRNA move to the P and E sites, respectively. Catalyzes the coordinated movement of the two tRNA molecules, the mRNA and conformational changes in the ribosome.

Publication Abstract from PubMed

The crystal structure of Thermus thermophilus elongation factor G without guanine nucleotide was determined to 2.85 A. This GTPase has five domains with overall dimensions of 50 x 60 x 118 A. The GTP binding domain has a core common to other GTPases with a unique subdomain which probably functions as an intrinsic nucleotide exchange factor. Domains I and II are homologous to elongation factor Tu and their arrangement, both with and without GDP, is more similar to elongation factor Tu in complex with a GTP analogue than with GDP. Domains III and V show structural similarities to ribosomal proteins. Domain IV protrudes from the main body of the protein and has an extraordinary topology with a left-handed cross-over connection between two parallel beta-strands.
