Human Immunodeficiency Virus Reverse Transcriptase

3’-Azido-3’-deoxythymidine 5’4riphosphate (AZTTP) was an efficient substrate for the human immunodeficiency virus 1 reverse transcriptase. It was incorporated into both homopolymer and defined sequence DNA-primed RNA templates and DNA-primed DNA templates. The substrate and inhibitor kinetics of both AZTTP and dTTP were dependent on the template-primer and reaction conditions used. dTMP was inc...

Conformational changes in HIV-1 reverse transcriptase induced by nonnucleoside reverse transcriptase inhibitor binding.

Nonnucleoside reverse transcriptase inhibitors (NNRTI) are a group of small hydrophobic compounds with diverse structures that specifically inhibit HIV-1 reverse transcriptase (RT). NNRTIs interact with HIV-1 RT by binding to a single site on the p66 subunit of the p66/p51 heterodimeric enzyme, termed the NNRTI-binding pocket (NNRTI-BP). This binding interaction results in both short-range and ...

Future of nonnucleoside reverse transcriptase inhibitors.

The nonnucleoside reverse transcriptase (RT) inhibitors (NNRTIs) are small molecules that bind to HIV-1 RT at a site distinct from the DNA polymerase active site of the enzyme and block retroviral reverse transcription via an allosteric mechanism of action (1). Nevirapine (NVP) was the first NNRTI approved in 1996 by the US Food and Drug Administration for the treatment of HIV-1 infection, foll...

Nonnucleoside reverse transcriptase inhibitors are chemical enhancers of dimerization of the HIV type 1 reverse transcriptase.

Nonnucleoside reverse transcriptase inhibitors (NNRTIs) are allosteric inhibitors of the HIV type 1 (HIV-1) reverse transcriptase (RT). Yeast grown in the presence of many of these drugs exhibited dramatically increased association of the p66 and p51 subunits of the HIV-1 RT as reported by a yeast two-hybrid assay. The enhancement required drug binding by RT; introduction of a drug-resistance m...

Human immunodeficiency virus mutagenesis during antiviral therapy: impact of drug-resistant reverse transcriptase and nucleoside and nonnucleoside reverse transcriptase inhibitors on human immunodeficiency virus type 1 mutation frequencies.

The development of antiviral drug resistance is an important problem in the treatment of human immunodeficiency virus type 1 (HIV-1) infection. Potent antiretroviral therapy is currently used for treatment, and typically consists of at least two reverse transcriptase (RT) inhibitors. We have previously reported that both drugs and drug-resistant RT mutants can increase virus mutation frequencie...
