Telomerase is a ribonucleoprotein (RNP) enzyme that requires an integral telomerase RNA (TR) subunit, in addition to the catalytic telomerase reverse transcriptase (TERT), for enzymatic function. The secondary structures of TRs from the three major groups of species, ciliates, fungi

Assembly of 30S ribosomes involves the hierarchical addition of ribosomal proteins that progressively stabilize the folded 16S rRNA. Here, we use three-color single molecule FRET to show how combinations of ribosomal proteins uS4, uS17 and bS20 in the 16S 5'

1. To investigate whether a direct protein-protein interaction between apoA-I and lecithin:cholesterol acyltransferase (LCAT) is necessary for the activation of the enzyme, apoA-I was labelled with N-methylisatoic anhydride at lysine residues. The intermolecular resonance energy transfer from tryptophan residues of

Many RNA structures are composed of simple secondary structure elements linked by a few critical tertiary interactions. SHAPE chemistry has made interrogation of RNA dynamics at single-nucleotide resolution straightforward. However, de novo identification of nucleotides involved in tertiary interactions remains

RNA (New York, N.Y.), 14(4), 675-684 (2008-02-13)
Riboswitches are highly structured cis-acting elements located in the 5'-untranslated region of messenger RNAs that directly bind small molecule metabolites to regulate gene expression. Structural and biochemical studies have revealed riboswitches experience significant ligand-dependent conformational changes that are coupled to
