>gnl|CDD|29498 cd00797, HP1_INT_C, Phage HP1 integrase, C-terminal catalytic domain. Bacteriophage HP1 and related integrases are found in eubacteria, plasmids and temperate bacteriophages of the P2 family. They belong to the DNA breaking-rejoining enzyme superfamily, which includes tyrosine recombinases and type IB topoisomerases. These enzymes share the same fold in their C-terminal catalytic domain containing six conserved active site residues and the overall reaction mechanism. The HP1 recombinase controls phage replication by site-specific recombination between the HP1 genome and the chromosomal DNA. It is a heterobifunctional DNA-binding protein, which recognizes two different DNA sequence motifs (type I and type II binding sites). The C-terminal catalytic domain of the HP1 integrase binds to the type I site, while the less conserved N-terminal domain is largely responsible for binding to the type II site.. Length = 158
