TRANSLATION INITIATION FACTOR 3 N-TERMINAL DOMAIN
Overview
The structures of the two domains of translational initiation factor IF3, from Bacillus stearothermophilus have been solved by X-ray crystallography, using single wavelength anomalous scattering and multiwavelength anomalous, diffraction. Each of the two domains has an alpha/beta topology, with an, exposed beta-sheet that is reminiscent of several ribosomal and other RNA, binding proteins. An alpha-helix that protrudes out from the body of the, N-terminal domain towards the C-terminal domain suggests that IF3 consists, of two RNA binding domains connected by an alpha-helix and that it may, bridge two regions of the ribosome. This represents the first high, resolution structural information on a translational initiation factor.
