WebApr 19, 2016 · INTRODUCTION. The ribonucleic acid (RNA) plays fundamental roles in biology, including the transmission of genetic information, regulation of gene expression and catalysis of biochemical reactions ().Many RNA molecules or their parts (domains or motifs) fold into stable three-dimensional (3D) structures that define, at least partially, their ability … WebAug 12, 1994 · The folding pathways of large, highly structured RNA molecules are largely unexplored. Insight into both the kinetics of folding and the presence of intermediates was provided in a study of the Mg 2+-induced folding of the Tetrahymena ribozyme by hybridization of complementary oligodeoxynucleotide probes. This RNA folds via a …

WebDec 12, 2024 · Riboswitches are natural biosensors that can regulate gene expression by sensing small molecules. Knowledge of the structural dynamics of riboswitches is crucial to elucidate their regulatory mechanism and develop RNA biosensors. In this work, we incorporated the fluorophore, Cy3, and its quencher, TQ3, into a full-length adenine … WebJan 5, 2024 · Thus, folding coupled to binding is a mechanism that reduces affinity compared with binding to the fully-folded protein. ... The results agreed in detail with those determined in vitro, and in addition identified the probable presence of bound RNA polymerase adjacent to the bound repressor in one site.
WebThe properties of the folded state of a protein, a compact, highly hydrogen bonded structure with a non-polar core, can be understood by considering the energetic terms that lead to the stability of the folded state. Proteins form a stable folded state if the standard energy difference, ΔG ∘ = G ∘ U − G ∘ N. WebBiomolecular structure is the intricate folded, three-dimensional shape that is formed by a molecule of protein, DNA, or RNA, and that is important to its function. The structure of …
WebApr 11, 2024 · In conclusion, we have developed a new chiral self-folding cavitand receptor based on calix [5]arene that allows efficient enantioselective molecular recognition of chiral quaternary ammonium guests. This is facilitated by the flexible nature of the host, leading to superior induced-fit and conformational selection phenomena in comparison with ... WebDepending on the RNA structure and sequence motifs, diverse protein-protein interfaces are generated during the initial assembly leading to different quaternary structures. Interestingly enough the assembly process is highly cooperative suggesting that the proteins might assemble on the RNA target during the transcription process to compete more easily with …
Nucleic acid quaternary structure refers to the interactions between separate nucleic acid molecules, or between nucleic acid molecules and proteins. The concept is analogous to protein quaternary structure, but as the analogy is not perfect, the term is used to refer to a number of different concepts in nucleic acids and is less commonly encountered. Similarly other biomolecules such as
