Organism
Sulfolobus solfataricus (strain ATCC 35092 / DSM 1617 / JCM 11322 / P2)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair. Interaction with PCNA enhances ligase activity. DNA polymerase I, DNA ligase and the flap endonuclease may be constitutively associated with the PCNA heterotrimer forming a scanning complex able to couple DNA synthesis and Okazaki fragment maturation.1 Publication

Catalytic activityi

ATP + (deoxyribonucleotide)(n) + (deoxyribonucleotide)(m) = AMP + diphosphate + (deoxyribonucleotide)(n+m).UniRule annotation

Cofactori

a divalent metal cation1 Publication

Enzyme regulationi

Ligase activity stimulated by PCNA heterotrimer.1 Publication

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 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.
