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

Retrovirology, 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 ...

Rapid metabolic pathway assembly and modification using serine integrase site-specific recombination [PDF]

, 2013
Synthetic biology requires effective methods to assemble DNA parts into devices and to modify these devices once made. Here we demonstrate a convenient rapid procedure for DNA fragment assembly using site-specific recombination by ϕC31 integrase.

Prophage Integrase Typing Is a Useful Indicator of Genomic Diversity in Salmonella enterica

Frontiers in Microbiology, 2017
Salmonella enterica is a bacterial species that is a major cause of illness in humans and food-producing animals. S. enterica exhibits considerable inter-serovar diversity, as evidenced by the large number of host adapted serovars that have been ...

Characterization of HIV-1 integrase interaction with human Ku70 protein and initial implications for drug targeting

Scientific Reports, 2017
Human Ku70/Ku80 protein is known to influence HIV-1 replication. One of the possible reasons may be the protection of integrase from proteasomal degradation by Ku70 subunit. We demonstrated that recombinant HIV-1 integrase and Ku70 form a stable complex,

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

mBio, 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.

Gated rotation mechanism of site-specific recombination by ϕC31 integrase [PDF]

, 2012
Integrases, such as that of the Streptomyces temperate bacteriophage ϕC31, promote site-specific recombination between DNA sequences in the bacteriophage and bacterial genomes to integrate or excise the phage DNA.

The Discovery of Indole-2-carboxylic Acid Derivatives as Novel HIV-1 Integrase Strand Transfer Inhibitors

Molecules, 2023
As an important antiviral target, HIV-1 integrase plays a key role in the viral life cycle, and five integrase strand transfer inhibitors (INSTIs) have been approved for the treatment of HIV-1 infections so far.

An Allosteric Mechanism for Inhibiting HIV-1 Integrase with a Small Molecule [PDF]

, 2009
HIV-1 integrase (IN) is a validated target for developing antiretroviral inhibitors. Using affinity acetylation and mass spectrometric (MS) analysis, we previously identified a tetra-acetylated inhibitor (2E)-3-[3,4-bis(acetoxy)phenyl]-2-propenoate-N ...

Mathematical model of a serine integrase-controlled toggle switch with a single input [PDF]

, 2018
Dual-state genetic switches that can change their state in response to input signals can be used in synthetic biology to encode memory and control gene expression.

Relationship between HIV integrase polymorphisms and integrase inhibitor susceptibility: An in silico analysis [PDF]

Heliyon, 2018
Integrase (IN) plays an essential role in HIV-1 replication, by mediating integration of the viral genome into the host cell genome. IN is a potential target of antiretroviral (ARV) therapeutic drugs such as ALLINI, Raltegravir (RAL), and Elvitegravir (EVG).
