CRYSTAL STRUCTURE OF T215Y MUTANT HIV-1 REVERSE TRANSCRIPTASE IN COMPLEX WITH 1051U91
OverviewOverview
Six structures of human immunodeficiency virus type 1 (HIV-1) reverse, transcriptase (RT) containing combinations of resistance mutations for, zidovudine (AZT) (M41L and T215Y) or lamivudine (M184V) have been, determined as inhibitor complexes. Minimal conformational changes in the, polymerase or nonnucleoside RT inhibitor sites compared to the mutant RTMC, (D67N, K70R, T215F, and K219N) are observed, indicating that such changes, may occur only with certain combinations of mutations. Model building M41L, and T215Y into HIV-1 RT-DNA and docking in ATP that is utilized in the, pyrophosphorolysis reaction for AZT resistance indicates that some, conformational rearrangement appears necessary in RT for ATP to interact, simultaneously with the M41L and T215Y mutations.
