In the treatment of HIV, the loose active site of the HIV-1 reverse transcriptase (RT) allows numerous nucleotide analogues to act as proviral DNA ‘chain-terminators’. Acyclic nucleotide phosphonate analogues (ANPs) represent a particular class of nucleotide analogue that does not possess a ribose moiety. The structural basis for their substrate efficiency regarding viral DNA polymerases is poorly understood.Lire l‘article
