It is carried out by one of the enzymes carried in the virus, called reverse transcriptase.

PMPA, he said, attacks the human immunodeficiency virus in the same way AZT does, by blocking a crucial viral enzyme called reverse transcriptase.

Dr. Baltimore won a Nobel Prize for discovering an enzyme called reverse transcriptase in retroviruses, which include H.I.V.

The nRTIs block an enzyme called reverse transcriptase, which is important to HIV production.

The class of compounds, called TIBO derivatives, apparently sabotage a process involving a virus enzyme called reverse transcriptase, the scientists said.

These three drugs all attack the virus at the same point, interfering with an enzyme called reverse transcriptase.

To replicate, H.I.V. uses an enzyme called reverse transcriptase to turn its genetic material, which is made of RNA, into DNA.

The main enzyme responsible for synthesis of DNA from an RNA template is called reverse transcriptase.

The research might focus on the protein synthesized by the virus when it first enters a cell, called reverse transcriptase, which catalyzes the step from RNA to DNA.

The enzyme, called reverse transcriptase, is used by the HIV virus to turn its genetic material into a form that can be incorporated into the genetic arrangement of a human cell.
