AbstractT4 RNA ligase 1 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. T4 RNA ligase 2 also catalyzes the joining of a 3′‐hydroxyl terminus of RNA to a 5′‐phosphorylated RNA or DNA; unlike T4 RNA ligase 1, this enzyme prefers double‐stranded ...

Ligase IV (LIG4) syndrome belongs to the group of hereditary disorders associated with impaired DNA damage response mechanisms. Subjects affected with this rare autosomal recessive disease exhibit microcephaly, unusual facial features, growth retardation, developmental delay, skin anomalies, and are typically pancytopenic.

Membrane associated RING-CH (MARCH) ubiquitin ligases control the stability, trafficking and function of important immunoreceptors, including MHC molecules and costimulatory molecule CD86. Regulation of the critical antigen presenting molecule MHC II by MARCH1 and the control of MARCH1 expression by inflammatory stimuli is a key step in the function of

Recent studies on eukaryotic DNA ligases are briefly reviewed. The two distinguishable enzymes from mammalian cells, DNA ligase I and DNA ligase II, have been purified to homogeneity and characterized biochemically. Two distinct DNA ligases have also been identified in Drosophila melanogaster embryos.

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,

The structure of a giant ubiquitin E3 ligase sheds light on its activation in a substrate-dependent manner and shows how a single E3 enzyme uses distinct recognition modules to confer substrate specificity.

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.

DNA ligases and ligase-based technologies
Clinical and Applied Immunology Reviews, 2001Abstract DNA ligases catalyze the strand joining reaction at a nick junction. The requirement of base-pair complementarity at the nick junction has been explored for development of ligase-based technologies for mutation detection. In oligonucleotide ligation assay (OLA), two DNA probes complementary to the target sequence are joined by DNA ligase ...

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.
