  Domain Name: DNA_ligase_A_N
DNA ligase N terminus. This region is found in many but not all ATP-dependent DNA ligase enzymes (EC:6.5.1.1). It is thought to be involved in DNA binding and in catalysis. In human DNA ligase I, and in Saccharomyces cerevisiae, this region was necessary for catalysis, and separated from the amino terminus by targeting elements. In vaccinia virus this region was not essential for catalysis, but deletion decreases the affinity for nicked DNA and decreased the rate of strand joining at a step subsequent to enzyme-adenylate formation.

Tips:
 If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position.

 The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs.

 Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below.
