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

The molecular basis of CRL4 ubiquitin ligase architecture, targeting and regulation [PDF]

open access: yes, 2013
Members of the CUL4-RBX1-DDB1 (CRL4) E3 ubiquitin ligase family regulate multiple cellular processes including development, transcription, and DNA repair.

Regulation of nucleotide excision repair by UV-DDB: prioritization of damage recognition to internucleosomal DNA [PDF]

open access: yes, 2011
How tightly packed chromatin is thoroughly inspected for DNA damage is one of the fundamental unanswered questions in biology. In particular, the effective excision of carcinogenic lesions caused by the ultraviolet (UV) radiation of sunlight depends on ...

The fanconi anemia DNA repair pathway is regulated by an interaction between ubiquitin and the E2-like fold domain of FANCL [PDF]

open access: yes, 2015
The Fanconi Anemia (FA) DNA repair pathway is essential for the recognition and repair of DNA interstrand crosslinks (ICL). Inefficient repair of these ICL can lead to leukemia and bone marrow failure.

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.

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.

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.

SUMO chain-induced dimerization activates RNF4 [PDF]

open access: yes, 2014
Dimeric RING E3 ligases interact with protein substrates and conformationally restrain the ubiquitin-E2-conjugating enzyme thioester complex such that it is primed for catalysis.

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 ...
