Hairpin structure formation
WebJun 7, 2024 · By promoting a β-hairpin structure via tryptophan zipper motifs or by using isoelectric forces, a P301L-containing tau peptide had an inhibited propensity to aggregate. WebHairpin loop structures are common motifs in folded nucleic acids. The 5′-GCGCAGC sequence in DNA forms a characteristic and stable trinucleotide hairpin loop flanked by a two basepair stem helix. To better understand the structure formation of this hairpin loop motif in atomic detail, we employed replica-exchange molecular dynamics (RexMD) …

A recent study has used fluorescence measurements to monitor the folding thermodynamics and kinetics of a 16-residue β-hairpin. In the present paper, we obtain the free energy surface and ...
WebA hairpin loop is an unpaired loop of messenger RNA (mRNA) that is created when an mRNA strand folds and forms base pairs with another section of the same strand. The resulting structure looks like a loop or a U-shape. Hairpins are a common type of secondary structure in RNA molecules. WebJan 7, 2024 · This study presents an adenosine (A)-based molecular beacon (MB) for selective detection of Naja atra cardiotoxin (CTX) that functions by utilizing the competitive binding between CTX and the poly(A) stem of MB to coralyne. The 5′- and 3′-end of MB were labeled with a reporter fluorophore and a non-fluorescent quencher, respectively. …
WebThe results indicate that for DNA the optimal loop consists of four or five residues. The observation that hairpins are formed for n less than 3 and that the stability of DNA hairpins is at its maximum for loop lengths of four to five residues is at variance with earlier findings for RNA. In the latter case the optimal loop size consists of six ...
