Novel Enzyme Shows Potential As An Anti-HIV Target

...ts human and nonhuman primate targets. The compact retrovirus encodes just 14 proteins, which play different roles in promoting viral infection and virulence. As a retrovirus, HIV uses the host’s cellular machinery—including RNA polymerases, which carry out transcription—to copy its RNA genome into DNA and infi...
