The rates of blunt-end and cohesive-end ligation of DNA by T4 DNA ligase are increased by orders of magnitude in the presence of high concentrations of a variety of nonspecific polymers such as polyethylene glycol, Ficoll, bovine plasma albumin, or glycogen. Blunt-end ligation of small self-complementary oligodeoxyribonucleotides is also stimulated. The use of polyethylene glycol 6000 in such systems is characterized in some detail. Conditions are suggested which either greatly increase the… Expand

Enzymatic Synthesis of Backbone‐Modified Oligonucleotides Using T4 DNA Ligase
TLDR
A small‐scale experiment is described to probe the efficiency of the ligation reaction of modified oligonucleotides in the presence of 3 M betaine and 10% PEG 8000, followed by large‐scale ligation with subsequent isolation of the ligated oligon nucleotide. Expand
Nonenzymatic plasmid ligation mediated by minor groove-binding molecules.
TLDR
The method uses the affinity of distamycin for the minor groove to join DNA ends together and compares favorably with T4 ligation for AT-rich cohesive termini, but in principle it could be extended to any restriction site. Expand
DNA Ligases
  • Stanley Tabor
  • Chemistry, Medicine
  • Current protocols in molecular biology
  • 2001
TLDR
Two ligases are used for nucleic acid research and their reaction conditions and applications are described in this unit; under normal reaction conditions, only T4 DNA ligase will ligate blunt ends. Expand
Ligation of single-stranded oligodeoxyribonucleotides by T4 RNA ligase.
TLDR
A set of reaction conditions are described which dramatically shorten the reaction time and give reproducible 40 to 60% ligation of DNA fragments of up to 40 bases in length, which open promising new fields of application to T4 RNA ligase. Expand
Efficient ligation and cloning of DNA fragments with 2-bp overhangs.
TLDR
This work presents a simple method for the efficient ligation of DNA fragments with 2-bp overhanging ends, ranging in size from 0.7 to 2.5 kbp, and provides a new molecular biology tool for researchers. Expand
Randomness and optimality in enhanced DNA ligation with crowding effects
Enzymatic ligation is essential for the synthesis of long DNA. However, the number of ligated products exponentially decays as the DNA synthesis proceeds in a random manner. The controlling ofExpand
Macromolecular crowding extends the range of conditions under which DNA polymerase is functional.
The nick-translation reaction of E. coli DNA polymerase I (Pol I) was used as a model system to demonstrate the ability of macromolecular crowding to alter the response of an enzyme to a number ofExpand
A single-molecule sequencing assay for the comprehensive profiling of T4 DNA ligase fidelity and bias during DNA end-joining
TLDR
Pacific Biosciences Single-Molecule Real-Time sequencing technology is applied to directly sequence the products of a highly multiplexed ligation reaction and has the potential to provide new insights into the thermodynamics of annealing and the kinetics of end-joining reactions. Expand
Comparative analysis of the end-joining activity of several DNA ligases
TLDR
This analysis revealed that T4 DNA ligase, the most common enzyme utilized for in vitro ligation, had its greatest activity on blunt- and 2-base overhangs, and poorest on 5′-single base overhanging, indicating active site structure plays a role in determining substrate preference. Expand
Classification of type-II restriction endonucleases and cloning of non-identical cohesive-end fragments without self-polymerization using nonpalindromic oligodeoxyribonucleotide adapters.
TLDR
Class-II ENases have been arranged into 16 different families according to the composition of the 5'-protruding sequences present after cleavage, and this system was extended to allow the joining of noncompatible ends by the use of nonpalindromic complementary oligodeoxyribonucleotides (NPCOs) containing two nucleotides protruding at each 5' end.
