Functioni

DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair. Can use both ATP and NAD+, but NAD+ may be a preferred nucleotide cofactor.1 Publication

Catalytic activityi

ATP + (deoxyribonucleotide)(n) + (deoxyribonucleotide)(m) = AMP + diphosphate + (deoxyribonucleotide)(n+m).UniRule annotation1 Publication
NAD+ + (deoxyribonucleotide)(n) + (deoxyribonucleotide)(m) = AMP + beta-nicotinamide D-ribonucleotide + (deoxyribonucleotide)(n+m).UniRule annotation1 Publication

Cofactori

Mg2+1 Publication, Zn2+1 PublicationNote: Not stimulated by Ca2+, Mn2+ and Ni2+.1 Publication

pH dependencei

Optimum pH is 7.5.1 Publication

Temperature dependencei

Optimum temperature is 80 degrees Celsius.1 Publication

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
