Size: 20 µg


Integrase catalyzes viral DNA integration into the host chromosome, by performing a series of DNA cutting and joining reactions. The enzyme activity takes place after virion entry into a cell and reverse transcription of the RNA genome in dsDNA. The full length HIV-1 integrase (288 amino acids) has three domains: the catalytic core, the C-terminal, and the N-terminal domains. Although all three domains are required for integration, it is thought that the catalytic core domain contains the active site responsible for catalysis of all the reactions of integration/disintegration.

Integration of retroviral DNA is an obligatory step of retrovirus replication because proviral DNA is the template for productive infection. Integrase, a retroviral enzyme, catalyses integration. The process of integration can be divided into two sequential reactions. The first one, named 3'-processing, corresponds to a specific endonucleolytic reaction which prepares the viral DNA extremities to be competent for the subsequent covalent insertion, named strand transfer, into the host cell genome by a trans-esterification reaction. The monoclonal antibody is an aid in the reasearch against HIV-1 and in the diagnostic test development.
