RPSBLAST alignment for GI: 254780490 and conserved domain: cd01182

>gnl|CDD|29503 cd01182, INT_REC_C, DNA breaking-rejoining enzymes, intergrase/recombinases, C-terminal catalytic domain. The tyrosine recombinase/integrase family share the same catalytic domain containing six conserved active site residues. The best-studied members of this diverse family include the bacteriophage lambda integrase, the bacteriophage P1 Cre recombinase, the yeast Flp recombinase and the bacterial XerD/C recombinases. Their overall reaction mechanism is essentially identical and involves cleavage of a single strand of a DNA duplex by nucleophilic attack of a conserved tyrosine to give a 3' phosphotyrosyl protein-DNA adduct. In the second rejoining step, a terminal 5' hydroxyl attacks the covalent adduct to release the enzyme and generate duplex DNA. Many intergrase/recombinases also have N-terminal domains, which show little sequence or structure similarity.. Length = 162
