CC -!- FUNCTION: With Ku forms a non-homologous end joining (NHEJ) repair
CC enzyme which repairs DNA double-strand breaks (DSB) with reduced
CC fidelity. Recognizes, processes and reseals DSBs, including repairs on
CC incompatible DSB which require 3'-resection, gap filling and ligation.
CC Anneals the 3' overhanging strands from opposing breaks to form a
CC gapped intermediate, which then can be extended in trans by using the
CC termini as primers for extension of the annealed break. Binds to the
CC recessed 5'-phosphate moiety of the downstream DNA strand forming a
CC stable synaptic complex even when the 3'-protruding ends of the
CC template DNA strands are not complementary. Has numerous activities;
CC gap filling copies the template strand, and prefers a 5'-phosphate in
CC the gap and rNTPS (PubMed:17174332, PubMed:17947582), DNA-directed DNA
CC or RNA polymerase on 5'-overhangs, terminal transferase (extending
CC ssDNA or blunt dsDNA in a non-templated fashion, preferentially with
CC rNTPs), DNA-dependent RNA primase (synthesizes short RNAs on unprimed
CC closed ssDNA) and 3'- to 5'-exonuclease on ssDNA (PubMed:15499016).
CC Isolated Pol domain (and presumably the holoenzyme) is able to form
CC complexes between 2 noncompatible protruding 3'-ends DNA ends via
CC microhomologous DNA strands, in a end-bridging function to which it
CC adds a templated nucleotide (PubMed:17947582). Minimal primer length is
CC 2 nucleotides (PubMed:21255731). {ECO:0000269|PubMed:15499016,
CC ECO:0000269|PubMed:17174332, ECO:0000269|PubMed:17947582,
CC ECO:0000269|PubMed:21255731}.
CC -!- FUNCTION: The preference of the polymerase domain for rNTPs over dNTPs
CC may be advantageous in dormant cells, where the dNTP pool is limiting.
CC -!- FUNCTION: In conjunction with endogenous or Mycobacterium phage Omega
CC Ku (AC Q853W0) can reconstitute NHEJ in Saccharomyces cerevisiae.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + (deoxyribonucleotide)n-3'-hydroxyl + 5'-phospho-
CC (deoxyribonucleotide)m = (deoxyribonucleotide)n+m + AMP +
CC diphosphate.; EC=6.5.1.1; Evidence={ECO:0000269|PubMed:12215643,
CC ECO:0000269|PubMed:16023671, ECO:0000269|PubMed:16476729};
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000305|PubMed:14985346, ECO:0000305|PubMed:15499016,

CC ECO:0000305|PubMed:21255731};
CC Note=Binds 4 Mn(2+); 2 Mn(2+) for polymerase/primase activity, 1 each
CC for 3-phosphoesterase and ligase. {ECO:0000305|PubMed:14985346,
CC ECO:0000305|PubMed:15499016, ECO:0000305|PubMed:16023671,
CC ECO:0000305|PubMed:17174332, ECO:0000305|PubMed:21255731};
CC -!- ACTIVITY REGULATION: The polymerase, exonuclease and ligase activities
CC are stimulated by Ku. Polymerase activity is inhibited by EDTA.
CC {ECO:0000269|PubMed:12215643, ECO:0000269|PubMed:16023671}.
CC -!- SUBUNIT: Monomer. Component of the NHEJ repair enzyme with mKu.
CC Interacts with Ku in the absence of DSB via the Pol domain. In
CC structures of the Pol domain with template DNA 2 Pol domains are bound
CC to microhomologous DNA complexes to form an end-bridging complex.
CC Probably interacts with Mycobacterium phage Omega and Corndog Ku
CC homologs (AC Q853W0, AC Q856K7). Interacts with Sir2; may form a
CC trimeric complex with LigD during NHEJ. {ECO:0000269|PubMed:12215643,
CC ECO:0000269|PubMed:14985346, ECO:0000269|PubMed:15499016,

CC ECO:0000269|PubMed:24239356}.
CC -!- DOMAIN: The N-terminal Mn(2+)-dependent polymerase/primase domain (Pol)
CC functions as an independent domain, binds DNA, is sufficient for DNA-
CC directed and non-DNA-directed DNA synthesis (PubMed:15778718) and
CC interacts with Ku (PubMed:16023671). {ECO:0000269|PubMed:15778718,
CC ECO:0000269|PubMed:16023671}.
CC -!- DOMAIN: The central 3'-phosphoesterase domain (PE) has exonuclease
CC activity probably constituted of 3'-ribonuclease and 3'-phosphatase
CC activity (PubMed:15499016). It does not function as an independent
CC domain (PubMed:16023671). {ECO:0000269|PubMed:15499016,
CC ECO:0000269|PubMed:16023671}.
CC -!- DOMAIN: The C-terminal ligase domain (Lig) binds dsDNA and functions as
CC an independent domain (PubMed:14985346, PubMed:16023671).
CC {ECO:0000269|PubMed:14985346, ECO:0000269|PubMed:16023671}.
CC -!- DISRUPTION PHENOTYPE: Not essential for growth, 80% reduction in NHEJ
CC (in strain Erdman). {ECO:0000269|PubMed:14985346}.
CC -!- MISCELLANEOUS: LigD has variable architecture; domain order can be
CC permutated, domains can be independently encoded, while some bacteria
CC lack the 3'-phosphoesterase domain entirely.
CC -!- MISCELLANEOUS: It is not clear whether there is a 5- to 3'-exonuclease
CC activity associated with the enzyme.
CC -!- SIMILARITY: In the N-terminal section; belongs to the LigD polymerase
CC family. {ECO:0000305}.
CC -!- SIMILARITY: In the central section; belongs to the LigD 3'-
CC phosphoesterase family. {ECO:0000305}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the ATP-dependent DNA
CC ligase family. {ECO:0000305}.
