Toward Understanding the Conformational Dynamics of RNA Ligation
Members of the genus <i>Trypanosoma</i>, which include the pathogenic species <i>Trypanosoma brucei</i> and <i>Trypanosoma cruzi</i>, edit their post-transcriptional mitochondrial RNA via a multiprotein complex called the editosome. In <i>T. brucei</i>, the RNA is nicked prior to uridylate insertion and deletion. Following editing, nicked RNA is religated by one of two RNA-editing ligases (<i>Tb</i>REL). This study describes a recent 70 ns molecular dynamics simulation of <i>Tb</i>REL1, an ATP-dependent RNA-editing ligase of the nucleotidyltransferase superfamily that is required for the survival of <i>T. brucei</i> insect and bloodstream forms. In this work, a model of <i>Tb</i>REL1 in complex with its full double-stranded RNA (dsRNA) substrate is created on the basis of the homologous relation between <i>Tb</i>REL1 and T4 Rnl2. The simulation captures <i>Tb</i>REL1 dynamics in the state immediately preceding RNA ligation, providing insights into the functional dynamics and catalytic mechanism of the kinetoplastid ligation reaction. Important features of RNA binding and specificity are revealed for kinetoplastid ligases and the broader nucleotidyltransferase superfamily
