  ABSTRACT  
 
The three-dimensional structure of the fMet-tRNA(fMet) -binding domain of translation initiation factor IF2 from Bacillus stearothermophilus has been determined by heteronuclear NMR spectroscopy. Its structure consists of six antiparallel beta-strands, connected via loops, and forms a closed beta-barrel similar to domain II of elongation factors EF-Tu and EF-G, despite low sequence homology. Two structures of the ternary complexes of the EF-Tu small middle dotaminoacyl-tRNA small middle dot GDP analogue have been reported and were used to propose and discuss the possible fMet-tRNA(fMet)-binding site of IF2.

Figure 4.
Figure 4 Overall organization of the antiparallel -strands of IF2 C-2. The arrows indicate the -strands that are numbered. The start and end of each strand is indicated. Strand -1 starts with a -bulge (residues 647 and 648).

Figure 5 Structural homology between IF2 C-2 and the elongation factors EF-Tu and EF-G. Ribbon representations of the C[ ]traces of: (A) domain II of T.aquaticus EF-Tu (Nissen et al., 1995); (B) B.stearothermophilus IF2 C-2; and (C) domain II of T.thermophilus EF-G (Ævarsson et al., 1994). The N- and C-termini are indicated in each structure.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
