Characterization of the purified FL and TR Dr-tRNA-LC.A, binding curves of titration of purified tRNA-LC with fluorescently labeled zebrafish tRNAIle. Error bars indicate SD. n = 3 (independent dilution series, measurements of all three replicas are shown). B, size analysis by DLS of purified FL (green) and TR (blue) tRNA-LC in the presence or the absence of tRNAIle. n = 5 (technical replicates). C, first derivative of thermal melting curves obtained for purified FL (green; right) and TR (blue; left) tRNA-LC in the presence or the absence of tRNAIle. Inflection points used for Tm value calculation are indicated by vertical lines. n = 5 (technical replicates). D, quantification of the presented results. DLS, dynamic light scattering; Dr-tRNA-LC, ligase complex from Danio rerio; FL, full-length; rH, hydrodynamic radius; TR, truncated LC; tRNA-LC, tRNA ligase complex.
