DNA ligase C-terminal domain; This is the C-terminal domain found in ATP-Dependent DNA Ligase from Bacteriophage T7. This domain has no ligase activity, however together with the N-terminal domain they bind to double-stranded DNA consistent with the idea that the DNA-binding site is between the domains in the intact protein. Furthermore, although the fold of domain 2 is very similar to a number of other proteins that bind single-stranded DNA, this domain does not bind to single-stranded DNA but instead has a high affinity for double-stranded DNA.

Adenylation domain of ATP-dependent DNA Ligases; ATP-dependent polynucleotide ligases catalyze phosphodiester bond formation using nicked nucleic acid substrates with the high energy nucleotide of ATP as a cofactor in a three step reaction mechanism. DNA ligases play a vital role in the diverse processes of DNA replication, recombination and repair. ATP-dependent ligases are present in many organisms such as viruses, bacteriophages, eukarya, archaea and bacteria. Some organisms express a variety of different ligases which appear to be targeted to specific functions. ATP-dependent DNA ligases have a highly modular architecture consisting of a unique arrangement of two or more discrete domains including a DNA-binding domain, an adenylation (nucleotidyltransferase (NTase)) domain, and an oligonucleotide/oligosaccharide binding (OB)-fold domain. The adenylation domain binds ATP and contains many of the active-site residues. The adenylation and C-terminal OB-fold domains comprise a catalytic core unit that is common to most members of the ATP-dependent DNA ligase family. The catalytic core unit contains six conserved sequence motifs (I, III, IIIa, IV, V and VI) that define this family of related nucleotidyltransferases.

DNA ligase D, ligase domain; DNA repair of double-stranded breaks by non-homologous end joining (NHEJ) is accomplished by a two-protein system that is present in a minority of prokaryotes. One component is the Ku protein (see TIGR02772), which binds DNA ends. The other is a DNA ligase, a protein that is a multidomain polypeptide in most of those bacteria that have NHEJ, a permuted polypeptide in Mycobacterium tuberculosis and a few other species, and the product of tandem genes in some other bacteria. This model represents the ligase domain.

DNA ligases play a vital role in the diverse processes of DNA replication, recombination and repair. ATP-dependent ligases are present in many organisms such as viruses, bacteriophages, eukarya, archaea and bacteria. There are three classes of ATP-dependent DNA ligase in eukaryotic cells (I, III and IV). DNA ligase IV is required for DNA non-homologous end joining pathways, including recombination of the V(D)J immunoglobulin gene segments in cells of the mammalian immune system. DNA ligase IV is stabilized by forming a complex with XRCC4, a nuclear phosphoprotein, which is phosphorylated by DNA-dependent protein kinase. DNA ligases have a highly modular architecture consisting of a unique arrangement of two or more discrete domains. The adenylation and C-terminal oligonucleotide/oligosaccharide binding (OB)-fold domains comprise a catalytic core unit that is common to all members of the ATP-dependent DNA ligase family.

Bacterial DNA ligases are divided into two broad classes: NAD-dependent and ATP-dependent. All bacterial species have a NAD-dependent DNA ligase (LigA). Some bacterial genomes contain multiple genes for DNA ligases that are predicted to use ATP as their cofactor, including Mycobacterium tuberculosis LigB, LigC, and LigD. This group is composed of archaeal DNA ligases and bacterial proteins similar to Mycobacterium tuberculosis LigB. Members of this group contain adenylation and C-terminal oligonucleotide/oligosaccharide binding (OB)-fold domains, comprising a catalytic core unit that is common to most members of the ATP-dependent DNA ligase family.

Adenylation domain of kDNA ligases and similar proteins; The mitochondrial DNA of parasitic protozoans is highly unusual.

The Oligonucleotide/oligosaccharide binding (OB)-fold domain of ATP-dependent DNA ligase LigD is a DNA-binding module that is part of the catalytic core unit; ATP-dependent polynucleotide ligases catalyze phosphodiester bond formation using nicked nucleic acid substrates with the high energy nucleotide of ATP as a cofactor in a three step reaction mechanism. DNA ligases play a vital role in the diverse processes of DNA replication, recombination and repair. ATP-dependent ligases are present in many organisms such as viruses, bacteriohages, eukarya, archaea and bacteria. Bacterial DNA ligases are divided into two broad classes: NAD-dependent and ATP-dependent. All bacterial species have a NAD-dependent DNA ligase (LigA). Some bacterial genomes contain multiple genes for DNA ligases that are predicted to use ATP as their cofactor, including Mycobacterium tuberculosis LigB, LigC, and LigD. This group is composed of Mycobacterium tuberculosis LigD and similar bacterial proteins. LigD, or DNA ligase D, catalyzes the end-healing and end-sealing steps during nonhomologous end joining. ATP dependent DNA ligases have a highly modular architecture consisting of a unique arrangement of two or more discrete domains including a DNA-binding domain, an adenylation (nucleotidyltransferase (NTase)) domain, and an oligonucleotide/oligosaccharide binding (OB)-fold domain.

The catalytic core unit contains six conserved sequence motifs (I, III, IIIa, IV, V and VI) that define this family of related nucleotidyltransferases. The OB-fold domain contacts the nicked DNA substrate and is required for the ATP-dependent DNA ligase nucleotidylation step. The RxDK motif (motif VI), which is essential for ATP hydrolysis, is located in the OB-fold domain.

DNA ligases play a vital role in the diverse processes of DNA replication, recombination and repair. ATP-dependent ligases are present in many organisms such as viruses, bacteriophages, eukarya, archaea and bacteria. There are three classes of ATP-dependent DNA ligases in eukaryotic cells (I, III and IV). DNA ligase III is not found in lower eukaryotes and is present both in the nucleus and mitochondria. It has several isoforms; two splice forms, III-alpha and III-beta, differ in their carboxy-terminal sequences. DNA ligase III-beta is believed to play a role in homologous recombination during meiotic prophase. DNA ligase III-alpha interacts with X-ray Cross Complementing factor 1 (XRCC1) and functions in single nucleotide Base Excision Repair (BER). The mitochondrial form of DNA ligase III originates from the nucleolus and is involved in the mitochondrial DNA repair pathway. This isoform is expressed by a second start site on the DNA ligase III gene. DNA ligases have a highly modular architecture consisting of a unique arrangement of two or more discrete domains. The adenylation and C-terminal oligonucleotide/oligosaccharide binding (OB)-fold domains comprise a catalytic core unit that is common to most members of the ATP-dependent DNA ligase family.
