Abstract: HIV-1 cross-resistance to ddC/3TC/ddI resulting from the K65R mutation may therefore involve selective alterations in substrate/inhibitor recognition.
Abstract: The K65R mutation in human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT) encodes cross-resistance to 2',3'-dideoxycytidine (ddC), 2',3'-dideoxy-3'-thiacytidine (3TC), and 2',3'-dideoxyinosine (ddI).
Abstract: We characterized the in vitro sensitivities of recombinant wild type (wt) and K65R mutant RT to dideoxynucleoside triphosphate (ddNTP) inhibitors, using a variety of primer-templates.
Abstract: With a heteropolymeric primer-template, the K65R mutant showed 10-fold reduced sensitivities to ddCTP, 3TCTP, and ddATP, and 4-fold reduced sensitivity
