ASV INTEGRASE CORE DOMAIN WITH HIV-1 INTEGRASE INHIBITOR Y3

Structural highlights

1a5w is a 1 chain structure with sequence from Rous sarcoma virus (strain schmidt-ruppin). Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:
Activity:	RNA-directed DNA polymerase, with EC number 2.7.7.49
Resources:	FirstGlance, OCA, RCSB, PDBsum

Function

[POL_RSVP] Capsid protein p27 forms the spherical core of the virus that encapsulates the genomic RNA-nucleocapsid complex (By similarity). The aspartyl protease mediates proteolytic cleavages of Gag and Gag-Pol polyproteins during or shortly after the release of the virion from the plasma membrane. Cleavages take place as an ordered, step-wise cascade to yield mature proteins. This process is called maturation. Displays maximal activity during the budding process just prior to particle release from the cell (By similarity).

Publication Abstract from PubMed

The x-ray structures of an inhibitor complex of the catalytic core domain of avian sarcoma virus integrase (ASV IN) were solved at 1.9- to 2.0-A resolution at two pH values, with and without Mn2+ cations. This inhibitor (Y-3), originally identified in a screen for inhibitors of the catalytic activity of HIV type 1 integrase (HIV-1 IN), was found in the present study to be active against ASV IN as well as HIV-1 IN. The Y-3 molecule is located in close proximity to the enzyme active site, interacts with the flexible loop, alters loop conformation, and affects the conformations of active site residues. As crystallized, a Y-3 molecule stacks against its symmetry-related mate. Preincubation of IN with metal cations does not prevent inhibition, and Y-3 binding does not prevent binding of divalent cations to IN. Three compounds chemically related to Y-3 also were investigated, but no binding was observed in the crystals. Our results identify the structural elements of the inhibitor that likely determine its binding properties.
