The viral enzyme reverse transcriptase

WebMar 1, 2024 · HIV Reverse Transcriptase. HIV reverse transcriptase (RT) is an asymmetric heterodimer which harbors two enzymatic domains: the RNA- and DNA-dependent DNA polymerase and the ribonuclease H (Li and De Clercq, 2016).After the viral entry of HIV particles, HIV RT produces the viral DNA genome based on the template of the single … WebThe Hepatitis B virus (HBV) polymerase is a multifunctional enzyme, with both RNA-dependent and DNA-dependent polymerase functions, as well as an RNase H function. It acts on the HBV pre-genomic RNA (pgRNA) to reverse transcribe it to form a new rcDNA molecule within a new capsid.

WebThe reverse transcriptase also possesses ribonuclease activity, which is used to degrade the RNA strand of the RNA-DNA hybrid. Lastly, the reverse transcriptase is used as a DNA polymerase to make a complementary copy to the ssDNA, yielding a dsDNA molecule. WebApr 9, 2024 · HIV nucleoside-analog reverse transcriptase inhibitors To replicate, HIV uses the enzyme reverse transcriptase to make a DNA copy of its RNA genome. A complementary copy of this DNA is then made to produce a double-stranded DNA intermediate which is able to insert into host cell chromosomes to form a provirus.
