Acrobatic HIV Enzyme Caught In Action
New mechanistic findings on a key HIV enzyme could help advance AIDS drug design, according to a report in Science (2008, 322, 1092). Reverse transcriptase (RT) is an essential enzyme in the life cycle of HIV and a target of AIDS drugs such as azidothymidine (AZT). But aspects of RT's mechanism have remained a mystery. Although the mechanism has been studied by crystallography and other techniques, the acrobatic moves RT undergoes while converting HIV's RNA . . .
