与3‘-叠氮-3’-脱氧胸苷(AZT)抗性相关的突变的存在增强了人类免疫缺陷病毒1型逆转录酶(RT)对末端链DNA的核苷酸依赖解锁作用。体内AZT抗性水平较高的突变组合,解锁活性的增加更大。通过在核苷酸底物中引入甲基,突变体和野生型活性之间的差异进一步扩大,而对于非芳香族底物,差异则减小,这表明这些突变可能促进了RT和芳香族结构之间的π-π相互作用。
Nucleotide-dependent unblocking of chain-terminated DNA by human immunodeficiency virus type 1 reverse transcriptase (RT) is enhanced by the presence of mutations associated with 3′-azido-3′-deoxythymidine (AZT) resistance. The increase in unblocking activity was greater for mutant combinations associated with higher levels of in vivo AZT resistance. The difference between mutant and wild-type activity was further enhanced by introduction of a methyl group into the nucleotide substrate and was decreased for a nonaromatic substrate, suggesting that π-π interactions between RT and an aromatic structure may be facilitated by these mutations.
