Abstract

We have studied selected mutants of human immunodeficiency virus type 2 (HIV-2) reverse transcriptase (RT) in a cell-free system in order to assess whether the mutant proteins exhibit a reduction in the sensitivity to nucleoside analog inhibitors similar to that of HIV-1 RT. We have modified, by site-directed mutagenesis, several of those amino acid residues so that their equivalent substitutions in HIV-1 RT have led to the formation of HIV-1 RT variants with the highest degree of resistance to dideoxynucleoside triphosphates (i.e., Glu-89-->Gly, Leu-74-->Val, and Ser-215-->Tyr [which is comparable to the Thr-215-->Tyr mutation of HIV-1 RT] and the double mutations Glu-89-->Gly/Ser-215-->Tyr and and Leu-74-->Val/Ser-215-->Tyr). The similarity found between resistance of the newly generated HIV-2 RT mutants to nucleoside analogs and that of the comparable mutants of HIV-1 RT can support the notion that the overall protein folding around the DNA polymerase active site in HIV-2 RT is quite similar to that of HIV-1 RT.

摘要

我们在无细胞系统中研究了人类免疫缺陷病毒2型(HIV-2)逆转录酶(RT)的特定突变体,以评估这些突变蛋白对核苷类似物抑制剂的敏感性是否降低,类似于HIV-1 RT。我们通过定点诱变修饰了其中几个氨基酸残基,使得它们在HIV-1 RT中的等效取代导致形成了对双脱氧核苷三磷酸具有最高抗性的HIV-1 RT变体(即,Glu-89→Gly、Leu-74→Val和Ser-215→Tyr [这与HIV-1 RT的Thr-215→Tyr突变相当] 以及双突变Glu-89→Gly/Ser-215→Tyr和Leu-74→Val/Ser-215→Tyr)。新产生的HIV-2 RT突变体对核苷类似物的抗性与HIV-1 RT的可比突变体之间的相似性可以支持这样一种观点,即HIV-2 RT中DNA聚合酶活性位点周围的整体蛋白质折叠与HIV-1 RT非常相似。
