==CATALYTIC DOMAIN OF BACTERIOPHAGE HP1 INTEGRASE==
-
HP1 integrase promotes site-specific recombination of the HP1 genome into, that of Haemophilus influenzae. The isolated C-terminal domain (residues, 165-337) of the protein interacts with the recombination site and contains, the four catalytic residues conserved in the integrase family. This domain, represents a novel fold consisting principally of well-packed alpha, helices, a surface beta sheet, and an ordered 17-residue C-terminal tail., The conserved triad of basic residues and the active-site tyrosine are, contributed by a single monomer and occupy fixed positions in a defined, active-site cleft. Dimers are formed by mutual interactions of the tail of, one monomer with an adjacent monomer; this orients active-site clefts, antiparallel to each other.

== Function ==
 +
[https://www.uniprot.org/uniprot/VINT_BPHC1 VINT_BPHC1] Integrase is necessary for integration of the phage into the host genome by site-specific recombination. In conjunction with excisionase, integrase is also necessary for excision of the prophage from the host genome.
