 AB    Prolonged therapy of AIDS patients with azidothymidine results in the
       development of resistance to the drug. This phenomenon is accompanied by
       the appearance of point mutations in the pol gene coding for reverse
       transcriptase (RT). Kinetic studies of interactions of wild type RT and
       its forms containing the above-mentioned mutations with substrates and
       azidothymidine 5'-triphosphate have been carried out. Considerable
       differences in the affinities of RT and the mutants for RNA and DNA
       heteropolymer templates were established. The mutations did not affect
       the RT affinity for dNTP; however, its location influenced considerably
       the inhibition of the reaction with azidothymidine 5'-triphosphate.
