A structure has been obtained for the loop E region of the 5S rRNA from Spinacia oleracia chloroplast ribosomes using residual dipolar coupling data as well as NOE, J coupling and chemical shift information. Even though the loop E sequence of this chloroplast 5S rRNA differs from that of Escherichia coli loop E at approximately 40% of its positions, its conformation is remarkably similar to that of E.coli loop E. Consistent with this conclusion, ribosomal protein L25 from E.coli, which binds to the loop E region of both intact E.coli 5S rRNA and to oligonucleotides containing that sequence, also binds to the chloroplast-derived oligonucleotide discussed here.
