RX PubMed=18593465; DOI=10.1186/1745-6150-3-26; RA Hou S., Makarova K.S., Saw J.H., Senin P., Ly B.V., Zhou Z., Ren Y., RA Wang J., Galperin M.Y., Omelchenko M.V., Wolf Y.I., Yutin N., RA Koonin E.V., Stott M.B., Mountain B.W., Crowe M.A., Smirnova A.V., RA Dunfield P.F., Feng L., Wang L., Alam M.; RT "Complete genome sequence of the extremely acidophilic methanotroph RT isolate V4, Methylacidiphilum infernorum, a representative of the RT bacterial phylum Verrucomicrobia."; RL Biol. Direct 3:26-26(2008). CC -!- FUNCTION: DNA ligase that catalyzes the formation of CC phosphodiester linkages between 5'-phosphoryl and 3'-hydroxyl CC groups in double-stranded DNA using NAD as a coenzyme and as the CC energy source for the reaction. It is essential for DNA CC replication and repair of damaged DNA (By similarity). CC -!- CATALYTIC ACTIVITY: NAD(+) + (deoxyribonucleotide)(n) + CC (deoxyribonucleotide)(m) = AMP + nicotinamide nucleotide + CC (deoxyribonucleotide)(n+m). CC -!- COFACTOR: Magnesium or manganese (By similarity). CC -!- SIMILARITY: Belongs to the NAD-dependent DNA ligase family. LigA CC subfamily. CC -!- SIMILARITY: Contains 1 BRCT domain.
