Synthesis of bisphosphonate derivatives of ATP by T4 DNA ligase, ubiquitin activating enzyme (E1) and other ligases

open access: closedBiochemical Pharmacology, 2008
T4 DNA ligase and the ubiquitin activating enzyme (E1), catalyze the synthesis of ATP beta,gamma-bisphosphonate derivatives. Concerning T4 DNA ligase: (i) etidronate (pC(OH)(CH(3))p) displaced the AMP moiety of the complex E-AMP in a concentration dependent manner; (ii) the K(m) values and the rate of synthesis k(cat) (s(-1)), determined for the ...

Identification of Novel Inhibitors of Escherichia coli DNA Ligase (LigA)

open access: yesMolecules, 2021
Present in all organisms, DNA ligases catalyse the formation of a phosphodiester bond between a 3′ hydroxyl and a 5′ phosphate, a reaction that is essential for maintaining genome integrity during replication and repair.

ATP-dependent DNA ligases. [PDF]

open access: bronzeGenome biology, 2002
By catalyzing the joining of breaks in the phosphodiester backbone of duplex DNA, DNA ligases play a vital role in the diverse processes of DNA replication, recombination and repair. Three related classes of ATP-dependent DNA ligase are readily apparent in eukaryotic cells.

A role for the ATP-dependent DNA ligase Lig E of Neisseria gonorrhoeae in biofilm formation [PDF]

open access: green, 2023
Abstract The ATP-dependent DNA ligase Lig E is present as an accessory DNA ligase in numerous proteobacterial genomes, including many disease-causing species. Here we have constructed a genomic Lig E knock-out in the obligate human pathogen Neisseria gonorrhoeae and characterised its growth and infection characteristics.

Analysis of the distribution and evolution of the ATP‐dependent DNA ligases of bacteria delineates a distinct phylogenetic group ‘Lig E [PDF]

open access: bronzeMolecular Microbiology, 2015
SummaryPrior to the discovery of a minimal ATP‐dependent DNA ligase in Haemophilus influenzae, bacteria were thought to only possess a NAD‐dependent ligase, which was involved in sealing of Okazaki fragments. We now know that a diverse range of bacterial species possess up to six of these accessory bacterial ATP‐dependent DNA ligases (b‐ADLs), which ...

Bleomycin-induced DNA repair by Saccharomyces cerevisiae ATP-dependent polydeoxyribonucleotide ligase [PDF]

open access: greenJournal of Bacteriology, 1988
In contrast to ligase-deficient (cdc9) Saccharomyces cerevisiae, which did not rejoin bleomycin-induced DNA breaks, ligase-proficient (CDC9) yeast cells eliminated approximately 90% of DNA breaks within 90 to 120 min after treatment. Experimental conditions restricted enzymatic removal of the unusual 3'-phosphoglycolate termini in DNA cleaved by ...

Synthesis of ATP derivatives of compounds of the mevalonate pathway (isopentenyl di- and triphosphate; geranyl di- and triphosphate, farnesyl di- and triphosphate, and dimethylallyl diphosphate) catalyzed by T4 RNA ligase, T4 DNA ligase and other ligases [PDF]

open access: greenBiochemical Pharmacology, 2009
Compounds of the mevalonate pathway containing a terminal di- or triphosphate (mev-PP or mev-PPP) were tested as substrates of several enzyme ligases (T4 RNA ligase, T4 DNA ligase, firefly luciferase and other ligases) for the synthesis of ATP derivatives of the mev-pppA or mev-ppppA type.

ATP‐ and NAD+‐dependent DNA ligases share an essential function in the halophilic archaeon Haloferax volcanii [PDF]

open access: closedMolecular Microbiology, 2005
SummaryDNA ligases join the ends of DNA molecules during replication, repair and recombination. ATP‐dependent ligases are found predominantly in the eukarya and archaea whereas NAD+‐dependent DNA ligases are found only in the eubacteria and in entomopoxviruses.
