 AB    Mechanisms of the effects of the dTTP analogues
       3'-azido-3'-deoxythymidine 5'-triphosphate (AZTTP) and
       3'-amino-3'-deoxythymidine 5'-triphosphate (NH2 TTP) upon the HIV-1
       reverse transcriptase (RT) are discussed. These compounds block the RT
       in vitro and do so by different kinetic mechanisms. Infidelity of
       replication is a hallmark of the HIV-1 RT, and replication errors by the
       enzyme on RNA and DNA templates are discussed. The enzyme's infidelity
       has ramifications for inhibition: On the one hand, the propensity to
       produce mutations enhances the ability of the virus to escape inhibitors
       whereas on the other hand, the infidelity of the reverse transcriptase
       may allow the development of imaginative inhibitor strategies.
