    New England Biolabs 5 dna adenylation kit
    Activity of the MthRnl and the K246A, K246Q and K97A mutants in different steps of the ligation reaction. (A) pH-dependence of <t>self-adenylation</t> activity of enzymes (step 1) in reactions with radioactive ATP. The reactions were carried out as described in the Methods and the products were resolved by an SDS-PAGE. Autoradiographs of the gels are shown. (B) pH-dependence of adenylation of 5’-phosphorylated, 3’-amino-blocked ssDNA (pDNA17-NH 2 ) (step 2) with wild type and the mutants of MthRnl under reaction conditions described in the Methods. The reaction products were separated by 15% urea-PAGE and visualized with SYBR Gold stain. (C) pH-dependence of deadenylation/hydrolysis of 5’ pre-adenylated <t>DNA</t> (AppDNA17-NH 2 ) with wild type and the mutants of MthRnl under reaction conditions described in the Methods. The products were analyzed on 15% urea-PAGE and stained with SYBR Gold. Enzymes used in each step of ligation reactions are indicated on the left. Position of DNA donor substrates and products are indicated on the right. The pH of the buffer is indicated at the bottom. The control (c) indicates the reaction without enzyme.

    Techniques:

    Ataluren effects on RFC-dependent termination of polypeptide synthesis. Cumulative distributions of ( a ) peptide and ( b ) tRNA dissociation times at indicated RFC concentrations, one also with 1 mM ataluren. Each cumulative distribution is constructed from ≥300 kinetic traces. Rates of dissociation of ( c ). peptide and ( d ). tRNA as a function of RFC concentration at different fixed ataluren concentrations. Error bars are ± s.e.m. for n = 250–750 trials. Normalized plots of ensemble experiments showing single exponential fits (solid lines) of decimated smoothed raw data (points) of atto647 pentapeptide release reaction measured by fluorescence anisotropy decay vs. time at 25 °C. e At indicated RFC concentrations. The control shows the near constancy of observed anisotropy in the absence of added RFC or ataluren. f At an RFC concentration of 0.0625 µM and varying ataluren concentrations. g The rates of dissociation of atto647 pentapeptide in ensemble experiments as a function of free RFC concentration at varying ataluren concentrations. Error bars are average deviation (a. d.) for n = 2–6 independent determinations. Values of n for each point are presented in Supplementary Table 5 . h Ataluren inhibition of normalized rates of dissociation of atto647 pentapeptide as measured by single molecule (red) and plate reader (black) assays. [eRF1], 32 nM; [eRF3], 0.2 µM and 0.8 µM in the single molecule and ensemble assays, respectively. Error bars are ± s.e.m. n ≥ 250 trials (single molecule) and ± a.d., n = 2 independent determinations (plate reader). i Rates of dissociation of atto647 labeled and unlabeled pentapeptide as measured by millipore filtration, calculated using both filtrate and filter retained values. Error bars are ± s.d., n = 8 independent measurements for all points except for the 4 min measurements, for which n = 11. [eRF1], 0.2 µM; [eRF3], 0.8 µM; POST5, 0.05 µM. j Ataluren inhibition of peptide and tRNA release when added at different times (4–25 s) following RFC addition to Stop-POST5. [RFC], 0.08 µM; [Ataluren], 1 mM. Values at zero-time correspond to simultaneous addition of ataluren and RFC. Error bars are ±s.e.m. for n ≥ 200 trials. Source data for all panels are provided as a Source Data file.
