The structure of ribosomal protein S17 from Bacillus stearothermophilus was investigated by two-dimensional homonuclear and heteronuclear magnetic resonance spectroscopy. The 1H and 15N chemical shift assignments are largely complete, and a preliminary structural characterization is presented. The protein consists of five beta-strands that form a single antiparallel beta-sheet with Greek-key topology. The beta-strands are connected by several extended loops, and two of these contain residue types that are frequently seen in the RNA-binding sites of proteins. Additionally, two point mutations that affect antibiotic resistance, translational fidelity, and ribosome assembly are located in these two regions of the protein. Since these potential RNA-binding sites are distributed over a large surface of the protein, it appears that the molecule may interact with several regions of 16S rRNA.
