RPSBLAST alignment for GI: 255764498 and conserved domain: cd00796

>gnl|CDD|29497 cd00796, INT_Rci, Rci recombinase, C-terminal catalytic domain. Rci enzymes are found in IncI1 incompatibility group plasmids such as R64. These recombinases belong to the superfamily of DNA breaking-rejoining enzymes, which share the same fold in their catalytic domain and the overall reaction mechanism. The R64 Rci recombinase mediates site specific recombination at the highly mobile DNA segments called shufflon located in the C-terminal region of the pilV gene, which determines the recipient specificity in liquid mating. This gene encodes a thin pilus component that recognizes recipient's receptors required for liquid mating. The recombination occurs between any of the seven inverted repeats that separate four DNA segments of the shufflon. The segments can be inverted independently or in groups, resulting in a complex DNA rearrangement. The catalytic domain of Rci is linked to a variable N-terminal domain, whose function is unknown..
