Adenylation domain of eukaryotic DNA Ligase I; 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. There are three classes of ATP-dependent DNA ligases in eukaryotic cells (I, III and IV). DNA ligase I is required for the ligation of Okazaki fragments during lagging-strand DNA synthesis and for base excision repair (BER). 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. The adenylation domain binds ATP and contains many of the active-site residues. DNA ligase I is the main replicative ligase in eukaryotes. The common catalytic core unit comprises 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.

artemis-SNM1C and related proteins; MBL-fold metallo-hydrolase domain; Includes the nuclease artemis (also known as SNM1C, SNM1 homolog C, SNM1-like protein and DNA cross-link repair 1C protein) which plays a role in V(D)J recombination/DNA repair. Purified artemis protein possesses single-strand-specific 5' to 3' exonuclease activity. Upon complex formation with, and phosphorylation by, DNA-dependent protein kinase, artemis gains endonucleolytic activity on hairpins and 5' and 3' overhangs. Inactivation of Artemis causes severe combined immunodeficiency (SCID). Members of this subgroup belong to the MBL-fold metallo-hydrolase superfamily which is comprised mainly of hydrolytic enzymes which carry out a variety of biological functions.

Adenylation domain of proteins similar to ATP-dependent polynucleotide ligases; ATP-dependent polynucleotide ligases catalyze the phosphodiester bond formation of nicked nucleic acid substrates using ATP as a cofactor in a three step reaction mechanism. This family includes ATP-dependent DNA and RNA ligases. DNA ligases play a vital role in the diverse processes of DNA replication, recombination and repair. 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 or nucleotidyltransferase (NTase) domain, and an oligonucleotide/oligosaccharide binding (OB)-fold domain. The adenylation domain binds ATP and contains many active site residues. Together with the C-terminal OB-fold domain, it comprises a catalytic core unit that is common to most members of the ATP-dependent DNA ligase family. The catalytic core contains six conserved sequence motifs (I, III, IIIa, IV, V and VI) that define this family of related nucleotidyltransferases including eukaryotic GRP-dependent mRNA-capping enzymes. The catalytic core contains both the active site as well as many DNA-binding residues. The RNA circularization protein from archaea and bacteria contains the minimal catalytic unit, the adenylation domain, but does not contain an OB-fold domain. This family also includes the m3G-cap binding domain of snurportin, a nuclear import adaptor that binds m3G-capped spliceosomal U small nucleoproteins (snRNPs), but doesn't have enzymatic activity.

Adenylation domain of putative bacterial ATP-dependent DNA ligases; 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 predicted bacterial 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. 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, including this group. The adenylation domain binds ATP and contains many of the active site residues.

Adenylation domain of uncharacterized fungal ATP-dependent DNA ligase-like proteins; 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. This group is composed of uncharacterized fungal proteins with similarity to ATP-dependent DNA ligases. 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.

DNA ligase D; Members of this protein family are DNA ligases involved in the repair of DNA double-stranded breaks by non-homologous end joining (NHEJ). The system of the bacterial Ku protein (TIGR02772) plus this DNA ligase is seen in about 20 % of bacterial genomes to date and at least one archaeon (Archeoglobus fulgidus). This model describes a central and a C-terminal domain. These two domains may be permuted, as in genus Mycobacterium, or divided into tandem ORFs, and therefore not be identified by this model. An additional N-terminal 3'-phosphoesterase (PE) domain present in some but not all examples of this ligase is not included in the seed alignment for this model; it only represents the central ATP-dependent ligase domain and the C-terminal polymerase domain. Most examples of genes for this ligase are adjacent to the gene for Ku. [DNA metabolism, DNA replication, recombination, and repair]

RNAaseJ, MBL-fold metallo-hydrolase domain; RNase J, also called Ribonuclease J, is a prokaryotic ribonuclease which plays a key part in RNA processing and in RNA degradation. It can act as an endonuclease which is specific for single-stranded regions of RNA irrespective of their sequence or location, and as a processive 5' exonuclease which only acts on substrates having a single phosphate or a hydroxyl at the 5' end. Many bacterial species have only one RNase J, but some, such as Bacillus subtilis, have two. Members of this subgroup belong to the MBL-fold metallo-hydrolase superfamily which is comprised mainly of hydrolytic enzymes which carry out a variety of biological functions.

Members of the MBL-fold metallohydrolase superfamily are mainly hydrolytic enzymes which carry out a variety of biological functions. The class B metal beta-lactamases (MBLs) for which this fold was named perform only a small fraction of the activities included in this superfamily.Activities carried out by superfamily members include class B beta-lactamases, hydroxyacylglutathione hydrolases, AHL (acyl homoserine lactone) lactonases, persulfide dioxygenases, flavodiiron proteins, cleavage and polyadenylation specificity factors such as the Int9 and Int11 subunits of Integrator, Sdsa1-like and AtsA-like arylsulfatases, 5'-exonucleases human SNM1A and yeast Pso2p, ribonuclease J and ribonuclease Z, cyclic nucleotide phosphodiesterases, insecticide hydrolases, and proteins required for natural transformation competence. Classical members of the superfamily are di-, or less commonly mono-, zinc-ion-dependent hydrolases, however the diversity of biological roles is reflected in variations in the active site metallo-chemistry.
