    New England Biolabs t4 dna ligase ligation protocol
    Effect of Inhibiting dsDNA on Enzyme Self-Adenylylation Rate. The determined rates for self-adenylylation of an uninhibited reaction, 2.5 μM <t>T4</t> DNA ligase (red) and 2.5 μM T4 DNA ligase and inhibited reactions 2.5 μM DNA (blue) and 10 μM DNA (green). The reactions were fit to a single exponential equation ( Eq 6 ) to determine the reaction rate. The uninhibited reaction was determined to have a single turnover rate of 20 s -1 ± 2 s -1 . While the 2.5 μM inhibited reaction had a single turnover rate of 2.8 s -1 ± 0.5 s -1 and the 10 μM inhibited reaction had a single turnover rate of 1.0 s -1 ± 1 s -1 . All reactions were performed a minimum of three times at 16°C. Error reported is the standard error for the replicates.

    15% denaturing PAGE for the ligation products of linkers A–B, C–D and linkers G–H. PAGE (10×10×0.03 cm, A:B = 29∶1, 7 M urea, 0.5x TBE) was run in 0.5 x TBE, 25°C, 100 V for 3.5 hrs in ( A )–( F ), or 4.3 hrs in ( G ). The ligation products were indicated by the arrows.

    Mapping of Illumina reads and MinION nanopore reads generated through <t>Sigma</t> <t>WTA2</t> and Qiagen REPLI-g to Everglades Virus strain EVG3–95. REPLI-g nanopore reads were exclusive to the final 4,000 basepairs (5′→ 3′), while Sigma nanopore reads were spread across the genome. Green shading of reads indicates alignment quality (dark regions align, light regions do not), and indicates ligated or otherwise generated chimeras. In the region where both sets of nanopore reads mapped, 7 out of 10 high-quality variants of 100% frequency detected by Illumina sequencing were also detected by nanopore sequencing. Only those variants detected by both Illumina and nanopore sequencing are shown. The ratio in parentheses below each variant is the ratio of Illumina reads containing the variant to Illumina read coverage at the specific location. The number of asterisks after the parentheses indicates how many nanopore reads also contained the same variant.

    Effect of Inhibiting dsDNA on Enzyme Self-Adenylylation Rate. The determined rates for self-adenylylation of an uninhibited reaction, 2.5 μM T4 DNA ligase (red) and 2.5 μM T4 DNA ligase and inhibited reactions 2.5 μM DNA (blue) and 10 μM DNA (green). The reactions were fit to a single exponential equation ( Eq 6 ) to determine the reaction rate. The uninhibited reaction was determined to have a single turnover rate of 20 s -1 ± 2 s -1 . While the 2.5 μM inhibited reaction had a single turnover rate of 2.8 s -1 ± 0.5 s -1 and the 10 μM inhibited reaction had a single turnover rate of 1.0 s -1 ± 1 s -1 . All reactions were performed a minimum of three times at 16°C. Error reported is the standard error for the replicates.

    Article Snippet: DsDNA inhibition likely also has an effect in commonly used molecular biology protocols, for example, the maximal recommended DNA concentration utilized in the ligation step for Next Generation Sequencing library preparation is ~20 ng/μL (NEB Ultra II), while the recommended DNA concentration in a standard sticky-end ligation is 4.38 ng/μL (NEB T4 DNA ligase ligation protocol).

    Techniques:

    T4 DNA Ligase Reaction Model. Modified reaction pathway to include the newly observed reactions in the previously described DNA ligation pathway that are inhibited by the presence of non-nicked dsDNA. A . Non-nicked dsDNA can bind to the deadenylylated form of the enzyme inhibition formation of the adenylylated form of the enzyme. B . Non-nicked dsDNA binds to the Lig-AMP form, preventing complexation with its preferred ds-nDNA substrate.

    k cat /K m Curve for T4 DNA Ligase. The data was obtained through titration of increasing concentrations of a 75mer-ds-nDNA substrate, reacted at 16°C to determine initial reaction rates. T4 DNA ligase concentrations used were 25 pM– 100 pM. The initial rates were plotted against their respective substrate concentrations and fit by: A . a classical uncompetitive substrate inhibition model ( Eq 2 ), where k cat and K m Values of 0.44 s -1 ± 0.3 s -1 and 4 nM ± 1 nM respectively, were determined. The K i value for substrate inhibition was calculated to be 590 nM ± 170 nM. B . A competitive substrate inhibition for a Bi-Bi Ping-Pong mechanism ( Eq 3 ) k cat and K m values of 0.48 s -1 ± 0.3 s -1 and 4 nM ± 1 nM respectively, were determined. The K i value for substrate inhibition was calculated to be 54 nM ± 15 nM. All data points are the average of at least three independent experiments, and the error reported is the standard deviation for the replicates.

    Various Inhibitors Effects on Rate of Nick Sealing. Various concentrations of dsDNA substrates were utilized as potential inhibitors of the T4 DNA ligase steady state ligation reaction on 20 nM of the 75mer-ds-nDNA substrate. All reactions were performed in the presence of 25 pM of T4 DNA ligase, a minimum of three times at 16°C. Error reported is the standard deviation for the replicates.

    Competition for ds-nDNA-Binding by dsDNA. Lane one contains 4 nM of the 75mer-ds-nDNA substrate alone, lanes 2–6 show shifting of the 4 nM substrate into a completely bound state as the concentration of T4 DNA ligase is increased from 100 nM– 1000 nM. Lanes 7–11 are of a titration of increasing concentrations of the unlabeled I-75-dsDNA oligo into a reaction containing 4 nM labeled nicked substrate and 1000 nM T4 DNA ligase. EMSA reactions were all performed and electrophoresed at room temperature (22°C).

    Mapping of Illumina reads and MinION nanopore reads generated through Sigma WTA2 and Qiagen REPLI-g to Everglades Virus strain EVG3–95. REPLI-g nanopore reads were exclusive to the final 4,000 basepairs (5′→ 3′), while Sigma nanopore reads were spread across the genome. Green shading of reads indicates alignment quality (dark regions align, light regions do not), and indicates ligated or otherwise generated chimeras. In the region where both sets of nanopore reads mapped, 7 out of 10 high-quality variants of 100% frequency detected by Illumina sequencing were also detected by nanopore sequencing. Only those variants detected by both Illumina and nanopore sequencing are shown. The ratio in parentheses below each variant is the ratio of Illumina reads containing the variant to Illumina read coverage at the specific location. The number of asterisks after the parentheses indicates how many nanopore reads also contained the same variant.

REPLI-g nanopore reads were exclusive to the final 4,000 basepairs (5′→ 3′), while Sigma nanopore reads were spread across the genome. Green shading of reads indicates alignment quality (dark regions align, light regions do not), and indicates ligated or otherwise generated chimeras. In the region where both sets of nanopore reads mapped, 7 out of 10 high-quality variants of 100% frequency detected by Illumina sequencing were also detected by nanopore sequencing. Only those variants detected by both Illumina and nanopore sequencing are shown. The ratio in parentheses below each variant is the ratio of Illumina reads containing the variant to Illumina read coverage at the specific location. The number of asterisks after the parentheses indicates how many nanopore reads also contained the same variant.

    Article Snippet: This may be primarily due to the lack of the ligation step in the Sigma WTA2 protocol.
