RPSBLAST alignment for GI: 254780882 and conserved domain: cd00800

>gnl|CDD|29501 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.. Length = 162
