5S ribosomal RNA is the smallest rRNA. Its Watson-Crick helices were identified more than 20 years ago, but the conformations of its loops have long defied analysis. One of the three arms of 5S rRNA, residues 69-106 in Escherichia coli, contains a 14-residue internal loop called loop E. The sequence of loop E is conserved within kingdoms, and is terminated by a pyrimidine-rich loop called loop D. Loop E is the binding site for the ribosomal protein L25 in the E. coli ribosome.
