    We have solved the crystal structure of the heat shock protein Hsp15, a newly isolated and very highly inducible heat shock protein that binds the ribosome. Comparison of its structure with those of two RNA-binding proteins, ribosomal protein S4 and threonyl-tRNA synthetase, reveals a novel RNA-binding motif. This newly recognized motif is remarkably common, present in at least eight different protein families that bind RNA. The motif's surface is populated by conserved, charged residues that define a likely RNA-binding site. An intriguing pattern emerges: stress proteins, ribosomal proteins and tRNA synthetases repeatedly share a conserved motif. This may imply a hitherto unrecognized functional similarity between these three protein classes.
