CATALYTIC DOMAIN OF BACTERIOPHAGE HP1 INTEGRASE
Overview
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.
