title: Interactions of the HIV-1 reverse transcriptase 'AZT-resistant' mutant with substrates and AZT-TP.
abstract: To investigate the biochemical basis of the HIV-1 resistance to AZT we obtained the RT mutant containing four amino acid substitutions by an oligonucleotide-directed mutagenesis technique. Enzymatic properties of the wild type and mutant RTs were compared. 'AZT-resistant' mutations in RT were shown to be associated with the reduced capability of AZT-TP to block the DNA- but not RNA-directed DNA synthesis.
