Crystal structures and snapshots along Tpt1-catalyzed phosphate transfer from nucleic acid to NAD+ [PDF]
Nature CommunicationsTpt1/TRPT1/KptA family proteins are evolutionarily conserved in all three domains of life. In fungi and plants, Tpt1 transfers 2’-PO4 2- from tRNA splice junction to NAD+, which is the final step of tRNA maturation and is critical for the function of ...

Evidence for a non-catalytic ion-binding site in multiple RNA-dependent RNA polymerases. [PDF]
PLoS ONE, 2012 A high-affinity divalent cation-binding site located proximal to the catalytic center has been identified in several RNA-dependent RNA polymerases (RdRps), but the characteristics of such a site have not been systematically studied.

Multiplexed RNA profiling by regenerative catalysis enables blood-based subtyping of brain tumors
Nature Communications, 2023 Current technologies to subtype glioblastoma (GBM), the most lethal brain tumor, require highly invasive brain biopsies. Here, we develop a dedicated analytical platform to achieve direct and multiplexed profiling of circulating RNAs in extracellular ...

Catalytic promiscuity in the RNA World may have aided the evolution of prebiotic metabolism.
PLoS Computational Biology, 2021 The Metabolically Coupled Replicator System (MCRS) model of early chemical evolution offers a plausible and efficient mechanism for the self-assembly and the maintenance of prebiotic RNA replicator communities, the likely predecessors of all life forms ...

Frontiers in Chemistry, 2022 Three protein targets from SARS-CoV-2, the viral pathogen that causes COVID-19, are studied: the main protease, the 2′-O-RNA methyltransferase, and the nucleocapsid (N) protein. For the main protease, the nucleophilicity of the catalytic cysteine C145 is

Modulation of RNase E activity by alternative RNA binding sites.
PLoS ONE, 2014 Endoribonuclease E (RNase E) affects the composition and balance of the RNA population in Escherichia coli via degradation and processing of RNAs. In this study, we investigated the regulatory effects of an RNA binding site between amino acid residues 25

Eukaryote-Specific Insertion Elements Control Human ARGONAUTE Slicer Activity
Cell Reports, 2013 We have solved the crystal structure of human ARGONAUTE1 (hAGO1) bound to endogenous 5′-phosphorylated guide RNAs. To identify changes that evolutionarily rendered hAGO1 inactive, we compared our structure with guide-RNA-containing and cleavage-active ...

Twenty years of "Lipid World": a fertile partnership with David Deamer [PDF]
, 2019 "The Lipid World" was published in 2001, stemming from a highly effective collaboration with David Deamer during a sabbatical year 20 years ago at the Weizmann Institute of Science in Israel.

Crystal structure of an RNA-cleaving DNAzyme
Nature Communications, 2017 RNA-cleaving DNA enzymes are catalytic DNA that can cleave RNA in a sequence-specific manner. Here, the authors report three crystal structures of the 8–17 DNAzyme that include the pre-catalytic state of the RNA cleavage reaction, providing insight into ...
