RBR E3 ubiquitin ligases: new structures, new insights, new questions [PDF]
, 2014 The RBR (RING-BetweenRING-RING) or TRIAD [two RING fingers and a DRIL (double RING finger linked)] E3 ubiquitin ligases comprise a group of 12 complex multidomain enzymes.

Closing the gap on DNA ligase [PDF]
Structure, 1996 The crystal structure of T7 DNA ligase complexed with ATP illuminates the mechanism of covalent catalysis by a superfamily of nucleotidyl transferases that includes the ATP-dependent polynucleotide ligases and the GTP-dependent mRNA capping enzymes.

Control of human adenovirus type 5 gene expression by cellular Daxx/ATRX chromatin-associated complexes [PDF]
, 2013 Death domain–associated protein (Daxx) cooperates with X-linked α-thalassaemia retardation syndrome protein (ATRX), a putative member of the sucrose non-fermentable 2 family of ATP-dependent chromatin-remodelling proteins, acting as the core ATPase ...

The Inhibitory Effect of Non-Substrate and Substrate DNA on the Ligation and Self-Adenylylation Reactions Catalyzed by T4 DNA Ligase. [PDF]
PLoS ONE, 2016 DNA ligases are essential both to in vivo replication, repair and recombination processes, and in vitro molecular biology protocols. Prior characterization of DNA ligases through gel shift assays has shown the presence of a nick site to be essential for ...

Structural and mechanistic conservation in DNA ligases [PDF]
Nucleic Acids Research, 2000 DNA ligases are enzymes required for the repair, replication and recombination of DNA. DNA ligases catalyse the formation of phosphodiester bonds at single-strand breaks in double-stranded DNA. Despite their occurrence in all organisms, DNA ligases show a wide diversity of amino acid sequences, molecular sizes and properties.

Labeling of Unique Sequences in Double-Stranded DNA at Sites of Vicinal Nicks Generated by Nicking Endonucleases [PDF]
, 2008 We describe a new approach for labeling of unique sequences within dsDNA under nondenaturing conditions. The method is based on the site-specific formation of vicinal nicks, which are created by nicking endonucleases (NEases) at specified DNA sites on ...

Mammalian DNA ligases. Biosynthesis and intracellular localization of DNA ligase I.
Journal of Biological Chemistry, 1990 Mammalian DNA ligase I is presumed to act in DNA replication. Rabbit antibodies against the homogeneous enzyme from calf thymus inhibited DNA ligase I activity and consistently recognized a single polypeptide of 125 kDa when cells from an established bovine kidney cell line (MDBK) were lysed rapidly by a variety of procedures and subjected to ...

DNA ligase IV syndrome; a review [PDF]
Orphanet Journal of Rare Diseases, 2016 DNA ligase IV deficiency is a rare primary immunodeficiency, LIG4 syndrome, often associated with other systemic features. DNA ligase IV is part of the non-homologous end joining mechanism, required to repair DNA double stranded breaks. Ubiquitously expressed, it is required to prevent mutagenesis and apoptosis, which can result from DNA double strand ...

Stealing the spotlight: CUL4-DDB1 ubiquitin ligase docks WD40-repeat proteins to destroy
Cell Division, 2007 Recent investigation of Cullin 4 (CUL4) has ushered this class of multiprotein ubiquitin E3 ligases to center stage as critical regulators of diverse processes including cell cycle regulation, developmental patterning, DNA replication, DNA damage and ...
