>cd00800 INT_Lambda_C Lambda integrase, C-terminal catalytic domain. Lambda-type integrases catalyze site-specific integration and excision of temperate bacteriophages and other mobile genetic elements to and from the bacterial host chromosome. They belong to the superfamily of DNA breaking-rejoining enzymes, which share the same fold in their catalytic domain and the overall reaction mechanism. The phage lambda integrase can bridge two different and well-separated DNA sequences called arm- and core-sites. The C-terminal domain binds, cleaves and re-ligates DNA strands at the core-sites, while the N-terminal domain is largely responsible for high-affinity binding to the arm-type sites.
