DNA_ligase_A_Npfam04675DNA ligase N terminus. This region is found in many but not all ATP-dependent DNA ligase enzymes (EC: 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.
