'''THE CRYSTAL STRUCTURE OF ELONGATION FACTOR G COMPLEXED WITH GDP, AT 2.7 ANGSTROMS RESOLUTION'''<br />


==Overview==
==THE CRYSTAL STRUCTURE OF ELONGATION FACTOR G COMPLEXED WITH GDP, AT 2.7 ANGSTROMS RESOLUTION==
Elongation factor G (EF-G) catalyzes the translocation step of protein, synthesis in bacteria, and like the other bacterial elongation factor, EF-Tu--whose structure is already known--it is a member of the GTPase, superfamily. We have determined the crystal structure of EF-G--GDP from, Thermus thermophilus. It is an elongated molecule whose large, N-terminal, domain resembles the G domain of EF-Tu, except for a 90 residue insert, which covers a surface that is involved in nucleotide exchange in EF-Tu, and other G proteins. The tertiary structures of the second domains of, EF-G and EF-Tu are nearly identical, but the relative placement of the, first two domains in EF-G--GDP resembles that seen in EF-Tu--GTP, not, EF-Tu--GDP. The remaining three domains of EF-G look like RNA binding, domains, and have no counterparts in EF-Tu.

Structural highlights

1efg is a 3 chain structure with sequence from Thermus thermophilus. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2.7Å
Ligands:
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

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.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
