ASV INTEGRASE CORE DOMAIN D64N MUTATION IN CITRATE BUFFER PH 6.0
|
OverviewOverview
Crystallographic studies of the catalytic core domain of avian sarcoma, virus integrase (ASV IN) have provided the most detailed picture so far of, the active site of this enzyme, which belongs to an important class of, targets for designing drugs against AIDS. Recently, crystals of an, inactive D64N mutant were obtained under conditions identical to those, used for the native enzyme. Data were collected at different pH values and, in the presence of divalent cations. Data were also collected at low pH, for the crystals of the native ASV IN core domain. In the structures of, native ASV IN at pH 6.0 and below, as well as in all structures of the, D64N mutants, the side chain of the active site residue Asx-64 (Asx, denotes Asn or Asp) is rotated by approximately 150 degrees around the, ...
