Frontiers in Molecular Biosciences, 2018 Cullin-RING (Really Interesting New Gene) E3 ubiquitin ligases (CRLs), the largest family of E3 ubiquitin ligases, are functional multi-subunit complexes including substrate receptors, adaptors, cullin scaffolds, and RING-box proteins.

Dynamics of phosphodiester synthesis by DNA ligase [PDF]
Proceedings of the National Academy of Sciences, 2008 Ligases are essential actors in DNA replication, recombination, and repair by virtue of their ability to seal breaks in the phosphodiester backbone. Ligation proceeds through a nicked DNA-adenylate intermediate (AppDNA), which must be sealed quickly to avoid creating a potentially toxic lesion.

Virtual high-throughput screening identifies mycophenolic acid as a novel RNA capping inhibitor. [PDF]
PLoS ONE, 2011 The RNA guanylyltransferase (GTase) is involved in the synthesis of the (m7)Gppp-RNA cap structure found at the 5' end of eukaryotic mRNAs. GTases are members of the covalent nucleotidyl transferase superfamily, which also includes DNA and RNA ligases ...

A Tobacco Homolog of DCN1 is Involved in Cellular Reprogramming and in Developmental Transitions [PDF]
, 2011 Plant proteomes show remarkable plasticity in reaction to environmental challenges and during developmental transitions. Some of this adaptability comes from ubiquitin-mediated protein destruction regulated by cullin-RING E3 ubiquitin ligases (CRLs ...

DNA unwinding and inhibition of T4 DNA ligase by anthracyclines
Nucleic Acids Research, 1988 The ability to alter DNA tertiary structure of ten anthracycline derivatives whose antitumor potency is known was studied by an assay that makes use of nicked circular DNA and bacteriophage T4 DNA ligase. This assay allows the detection of tertiary structure alterations caused by DNA binding of both intercalating and non-intercalating drugs.

New Aspects of HECT-E3 Ligases in Cell Senescence and Cell Death of Plants
Plants, 2019 Plant cells undergo massive orderly changes in structure, biochemistry, and gene expression during cell senescence. These changes cannot be distinguished from the hydrolysis/degradation function controlled by the ubiquitination pathway, autophagy, and ...

A role for SUMO modification in transcriptional repression and activation [PDF]
, 2007 Since the discovery of the SUMO (small ubiquitin-like modifier) family of proteins just over a decade ago, a plethora of substrates have been uncovered including many regulators of transcription.

The STUbL RNF4 regulates protein group SUMOylation by targeting the SUMO conjugation machinery
Nature Communications, 2017 SUMO and ubiquitin are key signal transducers in several cellular processes including the DNA-damage response. Here the authors describe a method for selective enrichment of ubiquitin substrates for E3 ligases from complex cellular proteomes and identify

NAD+-dependent DNA ligases of Mycobacterium tuberculosis and Streptomyces coelicolor [PDF]
, 2003 Sequencing of the genomes of Mycobacterium tuberculosis H37Rv and Streptomyces coelicolor A3(2) identified putative genes for an NAD+-dependent DNA ligase. We have cloned both open reading frames and overexpressed the protein products in Escherichia coli.
