Three-dimensional structure of the ribosomal translocase: elongation factor G from Thermus thermophilus.
EMBO J., 13:3669-3677, 1994

PubMed Abstract: 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.
