Abstract excerpt
Phosphonoformate (foscarnet) is a pyrophosphate (PP(i)) analogue and a potent inhibitor of human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT), acting through the PP(i) binding site on the enzyme. HIV-1 RT can unblock a chain-terminated DNA primer by phosphorolytic transfer of the terminal residue to an acceptor substrate (PP(i) or a nucleotide such as ATP) which also interacts with the PP(i)...
