Publication Abstract from PubMed Bacteriophage P2 is a temperate phage capable of integrating its DNA into the host genome by site-specific recombination upon lysogenization. Integration and excision of the phage genome requires P2 integrase, which performs recognition, cleavage and joining of DNA during these processes. This work presents the high-resolution crystal structure of the catalytic domain of P2 integrase, and analysis of the structure-function relationship of several previously identified non-functional P2 integrase mutants. The DNA binding area is characterized by a large positively charged patch, harboring key residues. The structure reveals potential for large dimer flexibility, likely essential for rearrangement of DNA strands upon integration and excision of the phage DNA.
