Asymmetric Organization of an AAA+ ATPase - Life Sciences Social Network In the previous article we spoke about the deal between McGraw-Hill and Engrade from Engrade’s perspective. Now let’s dig into the McGraw-Hill bit of the story. What’s Engrade and what does it do? When Hold took up Engrade full-time in 2010, he turned it into an enterprise education platform, and began selling it to schools. Riboswitches and the RNA World Ronald R. Breaker + Author Affiliations Correspondence: ronald.breaker@yale.edu Riboswitches are structured noncoding RNA domains that selectively bind metabolites and control gene expression (Mandal and Breaker 2004a; Coppins et al. 2007; Roth and Breaker 2009). Nearly all examples of the known riboswitches reside in noncoding regions of messenger RNAs where they control transcription or translation.

Folding of the hammerhead ribozyme: Pyrrolo-cytosine fluorescence separates core folding from global folding and reveals a pH-dependent conformational change Abstract The catalytic activity of the hammerhead ribozyme is limited by its ability to fold into the native tertiary structure. Analysis of folding has been hampered by a lack of assays that can independently monitor the environment of nucleobases throughout the ribozyme–substrate complex in real time. Here, we report the development and application of a new folding assay in which we use pyrrolo-cytosine (pyC) fluorescence to (1) probe active-site formation, (2) examine the ability of peripheral ribozyme domains to support native folding, (3) identify a pH-dependent conformational change within the ribozyme, and (4) explore its influence on the equilibrium between the folded and unfolded core of the hammerhead ribozyme. We conclude that the natural ribozyme folds in two distinct noncooperative steps and the pH-dependent correlation between core folding and activity is linked to formation of the G8-C3 base pair.
The seven wonders of the RNA world By Manny Ares and Tracy Johnson Right in the middle of the central dogma sits the RNA world, through which the information in DNA passes to create the functional state of the cell. This world is rife with nonprotein enzymes, mystery machines and unfathomed regulatory sophistication. Among its wonders are the ribosome, the spliceosome, catalytic RNAs, small transregulatory RNAs such as microRNAs and CRISPRs, large noncoding RNAs, riboswitches and RNA helicases. In the annual meeting thematic group “RNA: from Catalysis to Regulation,” we will explore the surface of this world in four parts. The elusive spliceosome
Additional roles of a peripheral loop–loop interaction in the Neurospora VS ribozyme Many RNAs contain tertiary interactions that contribute to folding the RNA into its functional 3D structure. In the VS ribozyme, a tertiary loop–loop kissing interaction involving stem–loops I and V is also required to rearrange the secondary structure of stem–loop I such that nucleotides at the base of stem I, which contains the cleavage–ligation site, can adopt the conformation required for activity. In the current work, we have used mutants that constitutively adopt the catalytically permissive conformation to search for additional roles of the kissing interaction in vitro.
