The GTP ...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. #3: ![]() Title: The Structure of Elongation Factor G in Complex with Gdp: Conformational Flexibility and Nucleotide Exchange Authors: Al-Karadaghi, S. / Aevarsson, A. / Garber, M. / Zheltonosova, J. / Liljas, A. #4: ![]() Title: Structure of a Mutant EF-G Reveals Domain III and Possibly the Fusidic Acid Binding Site Authors: Laurberg, M. / Kristensen, O. / Martemyanov, K. / Gudkov, A.T. / Nagaev, I. / Hughes, D. / Liljas, A. #5: Journal: J.Biol.Chem. / Year: 2001 Title: Mutations in the G-Domain of Elongation Factor G from Thermus Thermophilus Affect Both its Interaction with GTP and Fusidic Acid.
