Abstract: the subtype B mutant, with mutations Q7K, S37N, R41K, K45R, I54V, L63P, A71V, V82A and L90M, and the subtype F (wild type), naturally carrying mutations Q7K, I15V, E35D, M36I, S37N, R41K, R57K, D60E, Q61N, I62V, L63S, I64L and L89M, with res
Comparing the accumulation of active- and nonactive-site mutations in the HIV-1 protease.
Abstract: This variant possessed the ritonavir-resistance-associated mutations in the active-site (V32I and V82A) and nonactive-site mutations (K20R, L33F, M36I, L63P, A71V, and L90M).
Structural basis for coevolution of a human immunodeficiency virus type 1 nucleocapsid-p1 cleavage site with a V82A drug-resistant mutation in viral protease.
Abstract: AlaP2 does not fill the P2 pocket completely; PheP1' makes van der Waals interactions with Val82 that are lost with the V82A protease mutation.
Abstract: In response to the V82A drug-resistant protease mutation, the P2 alanine of NC-p1 mutates to valine (AP2V).
Abstract: To provide a structural rationale for HIV-1 protease binding to the NC-p1 cleavage site, we solved the crystal structures of inactive (D25N) WT and V82A HIV-1 proteases in complex with their respective WT and AP2V mutant NC-p1 substrates.

Abstract: Adjusted in a multivariate analysis, taking into account all the confounding factors, such as the nucleoside used, five mutations were combined in a resistance score associated with a reduced virological response to an SQV-plus-RTV regimen: L24I, I62V, V82A/F/T/S, I84V, and L90IM.

Abstract: The V82A mutation was found alone (66.6%) and it was found together with the I84V mutation in five samples (20.83%).
Abstract: Using LiPA P, mutations were detected in 16.21% of cases, with V82A being the most frequently detected mutation (15/24, 62.50%) in nine samples.
Viability of a drug-resistant human immunodeficiency virus type 1 protease variant: structural insights for better antiviral therapy.
Abstract: One of the first drug-resistant mutations to arise in the protease, particularly in patients receiving indinavir or ritonavir treatment, is V82A, which compromises the binding of these and other inhibitors but allows the virus to remain viable.
Abstract: The V82A mutation compromises these interactions with the drugs while not greatly affecting the substrate interactions, which is consistent with previously published kinetic data.
Abstract: To probe this drug resistance, we solved the crystal structures of three natural substrates and two commercial drugs in complex with an inactive drug-resistant mutant (D25N/V82A) HIV-1 protease.
Drug resistance mutations and outcome of second-line treatment in patients with first-line protease inhibitor failure on nelfinavir-containing HAART.
Abstract: Ten patients had D30N (38%), five patients had L90M (19%), two patients had V82A/F (8%) and two patients had M46I/L (8%).

Abstract: Baseline PI resistance mutations (L10F/I/V, K20M/R, E35D, R41K, I54V, L63P, V82A/F/T/S, I84V) identified by univariate analysis and included in a genotypic score and APV C(min) at week 8 were predictive of the virological response at week 12.
Overcoming resistance: virologic response to a salvage regimen with the combination of ritonavir plus indinavir.
Abstract: Several previously defined LPV mutations were found to have a stronger than average effect (e.g., M46I/L, I54V/T, V82A/F), and new variants at known positions (e.g., I54A/M/S, V82S) were identified.
