Mutations Located outside the Integrase Gene Can Confer Resistance to HIV-1 Integrase Strand Transfer Inhibitors

open access: yesmBio, 2017
Resistance to the integrase strand transfer inhibitors raltegravir and elvitegravir is often due to well-identified mutations in the integrase gene. However, the situation is less clear for patients who fail dolutegravir treatment.

Comparative biochemical analysis of HIV-1 subtype B and C integrase enzymes [PDF]

open access: yesRetrovirology, 2009
Background Integrase inhibitors are currently being incorporated into highly active antiretroviral therapy (HAART). Due to high HIV variability, integrase inhibitor efficacy must be evaluated against a range of integrase enzymes from different subtypes ...

Variable orthogonality of serine integrase interactions within the ϕC31 family [PDF]

open access: yesScientific Reports
Serine integrases are phage- (or mobile element-) encoded enzymes that catalyse site-specific recombination reactions between a short DNA sequence on the phage genome (attP) and a corresponding host genome sequence (attB), thereby integrating the phage ...

Integrase and integration: biochemical activities of HIV-1 integrase [PDF]

open access: yesRetrovirology, 2008
Integration of retroviral DNA is an obligatory step of retrovirus replication because proviral DNA is the template for productive infection. Integrase, a retroviral enzyme, catalyses integration. The process of integration can be divided into two sequential reactions.

Integrase illuminated [PDF]

open access: yesEMBO reports, 2010
Antiretroviral drugs to prevent integration of the HIV viral genome into chromosomes are undergoing clinical trials, yet they have been developed with an imperfect understanding of their mechanism of action. The recent crystal structure of the major viral protein integrase from a related, little‐known retrovirus, has finally provided insight into how ...

Resistance to Integrase Inhibitors [PDF]

open access: yesViruses, 2010
Integrase (IN) is a clinically validated target for the treatment of human immunodeficiency virus infections and raltegravir exhibits remarkable clinical activity. The next most advanced IN inhibitor is elvitegravir. However, mutant viruses lead to treatment failure and mutations within the IN coding sequence appear to confer cross-resistance.

Synthesis of programmable integrases [PDF]

open access: yesProceedings of the National Academy of Sciences, 2009
Accurate modification of the 3 billion-base-pair human genome requires tools with exceptional sequence specificity. Here, we describe a general strategy for the design of enzymes that target a single site within the genome. We generated chimeric zinc finger recombinases with cooperative DNA-binding and catalytic specificities that integrate transgenes ...

Genetic Diversity and Low Therapeutic Impact of Variant-Specific Markers in HIV-1 Pol Proteins

open access: yesFrontiers in Microbiology, 2022
The emergence and spread of new HIV-1 variants pose a challenge for the effectiveness of antiretrovirals (ARV) targeting Pol proteins. During viral evolution, non-synonymous mutations have fixed along the viral genome, leading to amino acid (aa) changes ...

Retroviral Integrase: Then and Now [PDF]

open access: yesAnnual Review of Virology, 2015
The retroviral integrases are virally encoded, specialized recombinases that catalyze the insertion of viral DNA into the host cell's DNA, a process that is essential for virus propagation. We have learned a great deal since the existence of an integrated form of retroviral DNA (the provirus) was first proposed by Howard Temin in 1964. Initial studies

Resistance to inhibitors of the human immunodeficiency virus type 1 integration

open access: yesBrazilian Journal of Infectious Diseases, 2010
This review will summarize the role of integrase in HIV-1 infection, the mechanism of integrase inhibitors and resistance with an emphasis on raltegravir (RAL), the first integrase inhibitor licensed to treat HIV-1 infection.
