Organism
Pseudomonas aeruginosa (strain ATCC 15692 / DSM 22644 / CIP 104116 / JCM 14847 / LMG 12228 / 1C / PRS 101 / PAO1)
Status
Functioni
With LigD forms a non-homologous end joining (NHEJ) DNA repair enzyme, which repairs dsDNA breaks with reduced fidelity. Stimulates rNTP addition to DSB and end joining (ligation) of linear DNA by LigD, on 3'-overhangs and probably also 5'-overhangs and blunt dsDNA breaks. Binds both ends of linear dsDNA protecting it from exonuclease activity.1 Publication

Subunit structurei
Homodimer, may form higher-order multimers on DNA. Non-dimerized protein does not stimulate LigD ligase activity. Probably interacts with LigD.
