Structure Motif Annotation: Mechanism and Catalytic Site Atlas M-CSA Database Homepage

Chains	Enzyme Name	Description	Catalytic Residues
A	DNA ligase (NAD+) M-CSA #450	DNA ligases catalyse the formation of phosphodiester bonds at single-strand breaks in double stranded DNA and are required in DNA replication, repair and recombination. DNA ligases are also used extensively for in vitro DNA manipulation and cloning techniques. Eukaryotic, viral and achaebacteria encoded enzyme al require ATP, where as NAD+ requiring DNA ligases are found exclusively in eubacteria.
