On ubiquitin ligases and cancer
Human Mutation, 2005Protein kinase genes account for almost 10% of all currently known cancer genes, highlighting the role of signal transduction in oncogenesis. A reexamination of the literature and available databases shows that E3 ubiquitin ligases are also key mediators of tumorigenesis. Altogether kinase and E3 genes represent more than 15% of the known cancer genes,

Nature, 1997
The preparation of synthetic molecules showing the remarkable efficiencies characteristic of natural biopolymer catalysts remains a formidable challenge for chemical biology. Although significant advances have been made in the understanding of protein structure and function, the de novo construction of such systems remains elusive.

AbstractDNA joining enzymes play an essential role in the maintenance of genomic integrity and stability. Three mammalian genes encoding DNA ligases, LIG1, LIG3 and LIG4, have been identified. Since DNA ligase II appears to be derived from DNA ligase III by a proteolytic mechanism, the three LIG genes can account for the four biochemically distinct DNA

Essays in Biochemistry, 2005
The selectivity of the ubiquitin–26 S proteasome system (UPS) for a particular substrate protein relies on the interaction between a ubiquitin-conjugating enzyme (E2, of which a cell contains relatively few) and a ubiquitin–protein ligase (E3, of which there are possibly hundreds).

Biochemical purification has identified a new component of the Fanconi anemia complex. The protein has ubiquitin ligase activity and may be the long-sought enzyme responsible for monoubiquitination of FANCD2.

AbstractThe DNA ligase enzyme family catalyzes the formation of a phosphodiester bond between juxtaposed 5′‐phosphate and 3′‐hydroxyl termini in duplex DNA. This activity can seal nicks in duplex DNA or join double‐stranded DNA fragments having either blunt or cohesive ends.

Methods, 1996
The combination of synthetic oligonucleotide probes and DNA ligases is central to several recently developed genetic assays. Among the advantages of ligase-mediated gene detection is that ligation of probe pairs provides highly specific detection of unique DNA sequences in genomic samples.

AbstractDNA ligases catalyze the formation of phosphodiester bonds between juxtaposed 5' phosphate and a 3'‐hydroxyl terminus in duplex DNA. This activity can repair single‐stranded nicks in duplex DNA and join duplex DNA restriction fragments having either blunt ends or homologous cohesive ends. Two ligases are used for nucleic acid research and their

AbstractT4 RNA ligase, the product of the phage gene 63, is purified from phage‐infected cells. It catalyzes the ATP‐dependent covalent joining of single‐stranded 5'‐phosphoryl termini of DNA or RNA to single‐stranded 3'‐hydroxyl termini of DNA or RNA. This unit describes specific reaction conditions as well as applications such as radioactive labeling
