Biological and Structural Analyses of New Potent Allosteric Inhibitors of HIV-1 Integrase.

The construct is of HIV-1 integrase with the following domain swap: The C-Terminal Domain of HIV-1 integrase (from residues 220 to 288) is followed by the Catalytic Core Domain of HIV-1 integrase (from residues 50 to 212). In addition, there are the following mutations: F185K and W243E. The residue numbers are correct in the structure. Because the linker is not defined in the electron density map, we do not know for sure which CTD is linked to which CCD in the lattice formation. We have therefore kept each domain as a separate chain. This chain is CTD There are 2 copies of CTD and CCD in the asymmetric unit. We cannot determine how they are connected in the crystal lattice.,The construct is of HIV-1 integrase with the following domain swap: The C-Terminal Domain of HIV-1 integrase (from residues 220 to 288) is followed by the Catalytic Core Domain of HIV-1 integrase (from residues 50 to 212).
