CC   -!- FUNCTION: With LigD forms a non-homologous end joining (NHEJ) DNA
CC       repair enzyme, which repairs dsDNA breaks with reduced fidelity. Binds
CC       linear dsDNA with 5'- and 3'- overhangs but not closed circular dsDNA
CC       nor ssDNA. Recruits and stimulates the ligase activity of LigD.
CC       {ECO:0000255|HAMAP-Rule:MF_01875}.
CC   -!- SUBUNIT: Homodimer. Interacts with LigD. {ECO:0000255|HAMAP-
CC       Rule:MF_01875}.
CC   -!- SIMILARITY: Belongs to the prokaryotic Ku family. {ECO:0000255|HAMAP-
CC       Rule:MF_01875}.
