This entry represents the primase-polymerase domain (Prim-Pol) of bacterial LigD proteins, such as LigD from Pseudomonas aeruginosa and Mycobacterium tuberculosis. LigD, together with Ku protein, is required for nonhomologous end-joining (NHEJ)-mediated repair of DNA double-strand breaks (DSB). This domain belongs to the archaeal/eukaryal primase (AEP) superfamily and mediates several nucleotidyl transferase activities, including DNA-dependent RNA primase, terminal transferase and DNA-dependent DNA/RNA gap-filling polymerase activities [1-5].
