CORE DOMAIN OF HIV-1 INTEGRASE COMLEXED WITH MG++ AND 1-(5-CHLOROINDOL-3-YL)-3-HYDROXY-3-(2H-TETRAZOL-5-YL)-PROPENONE
Overview
HIV integrase, the enzyme that inserts the viral DNA into the host, chromosome, has no mammalian counterpart, making it an attractive target, for antiviral drug design. As one of the three enzymes produced by HIV, it, can be expected that inhibitors of this enzyme will complement the, therapeutic use of HIV protease and reverse transcriptase inhibitors. We, have determined the structure of a complex of the HIV-1 integrase core, domain with a novel inhibitor, 5ClTEP, 1-(5-chloroindol-3-yl)-3-hydroxy-3-(2H-tetrazol-5-yl)-pro penone, to 2.1-A, resolution. The inhibitor binds centrally in the active site of the, integrase and makes a number of close contacts with the protein. Only, minor changes in the protein accompany inhibitor binding. This inhibitor, complex will provide a platform for structure-based design of an, additional class of inhibitors for antiviral therapy.
About this Structure
1QS4 is a Single protein structure of sequence from Human immunodeficiency virus 1 with MG and 100 as ligands. Active as RNA-directed DNA polymerase, with EC number 2.7.7.49 Full crystallographic information is available from OCA.
