Thermostable DNA ligases from hyperthermophiles in biotechnology

open access: yesFrontiers in Microbiology, 2023
DNA ligase is an important enzyme ubiquitous in all three kingdoms of life that can ligate DNA strands, thus playing essential roles in DNA replication, repair and recombination in vivo.

DNA Ligase I, the Replicative DNA Ligase [PDF]

open access: yes, 2012
Multiple DNA ligation events are required to join the Okazaki fragments generated during lagging strand DNA synthesis. In eukaryotes, this is primarily carried out by members of the DNA ligase I family. The C-terminal catalytic region of these enzymes is composed of three domains: a DNA binding domain, an adenylation domain and an OB-fold domain.

Identification of the DNA repair defects in a case of Dubowitz syndrome. [PDF]

open access: yesPLoS ONE, 2013
Dubowitz Syndrome is an autosomal recessive disorder with a unique set of clinical features including microcephaly and susceptibility to tumor formation. Although more than 140 cases of Dubowitz syndrome have been reported since 1965, the genetic defects

DNA ligase 1 deficient plants display severe growth defects and delayed repair of both DNA single and double strand breaks

open access: yesBMC Plant Biology, 2009
Background DNA ligase enzymes catalyse the joining of adjacent polynucleotides and as such play important roles in DNA replication and repair pathways. Eukaryotes possess multiple DNA ligases with distinct roles in DNA metabolism, with clear differences ...

A case report of an adolescent with ligase-4 deficiency and the potential dangers of ionizing radiation in this rare patient population

open access: yesRadiology Case Reports, 2021
DNA ligase IV deficiency is a rare disorder characterized by mutations in the LIG4 gene. Mutations in this gene cause a wide array of phenotypes, many of which are fatal early in life. We present an adolescent patient with heterozygous LIG4 mutations and

Detection of ligation products of DNA linkers with 5'-OH ends by denaturing PAGE silver stain. [PDF]

open access: yesPLoS ONE, 2012
To explore if DNA linkers with 5'-hydroxyl (OH) ends could be joined by commercial T4 and E. coli DNA ligase, these linkers were synthesized by using the solid-phase phosphoramidite method and joined by using commercial T4 and E. coli DNA ligases.

Identification of a novel motif in DNA ligases exemplified by DNA ligase IV [PDF]

open access: yesDNA Repair, 2006
DNA ligase IV is an essential protein that functions in DNA non-homologous end-joining, the major mechanism that rejoins DNA double-strand breaks in mammalian cells. LIG4 syndrome represents a human disorder caused by mutations in DNA ligase IV that lead to impaired but not ablated activity.

The phage T4 DNA ligase in vivo improves the survival-coupled bacterial mutagenesis

open access: yesMicrobial Cell Factories, 2019
Background Microbial mutagenesis is an important avenue to acquire microbial strains with desirable traits for industry application. However, mutagens either chemical or physical used often leads narrow library pool due to high lethal rate.

The phage T4 DNA ligase mediates bacterial chromosome DSBs repair as single component non-homologous end joining

open access: yesSynthetic and Systems Biotechnology, 2019
DNA double-strand breaks (DSBs) are one of the most lethal forms of DNA damage that is not efficiently repaired in prokaryotes. Certain microorganisms can handle chromosomal DSBs using the error-prone non-homologous end joining (NHEJ) system and ...

Bacteriophage origin of some minimal ATP-dependent DNA ligases: a new structure from Burkholderia pseudomallei with striking similarity to Chlorella virus ligase

open access: yesScientific Reports, 2021
DNA ligases, the enzymes responsible for joining breaks in the phosphodiester backbone of DNA during replication and repair, vary considerably in size and structure.
