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:0000256|HAMAP-Rule:MF_01875}.
CC -!- SUBUNIT: Homodimer. Interacts with LigD. {ECO:0000256|HAMAP-
CC Rule:MF_01875}.
CC -!- SIMILARITY: Belongs to the prokaryotic Ku family. {ECO:0000256|HAMAP-
CC Rule:MF_01875}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:PWA12673.1}.
