NNRTIs, such as nevirapine, directly inhibit HIV reverse transcriptase by binding to the enzyme's catalytic site, thereby blocking the conversion of viral RNA to DNA.
NNRTIs (Non-Nucleoside Reverse Transcriptase Inhibitors) like nevirapine directly bind to the reverse transcriptase enzyme to block its catalytic site, preventing HIV RNA to dsDNA conversion.
| Front | What reverse transcriptase inhibitors work by directly binding the reverse transcriptase enzyme? |
|---|---|
| Back | NNRTIs → original genetic information from HIV is in the form of RNA and reverse transcriptase is needed to convert ssRNA to dsDNA → two classes of reverse transcriptase inhibitors → Non-Nucleoside Reverse Transcriptase Inhibitors (nevirapine) which bind enzyme directly to block catalytic site → Nucleoside analogue Reverse Transcriptase Inhibitors (zidovudine) which are incorporated into DNA strand to prevent elongation |
