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

Retrovirology, 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]

EMBO 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 ...

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 ...

The integrase of genomic island GIsul2 mediates the mobilization of GIsul2 and ISCR-related element CR2-sul2 unit through site-specific recombination

Frontiers in Microbiology, 2022
In the worldwide health threat posed by antibiotic-resistant bacterial pathogens, mobile genetic elements (MGEs) play a critical role in favoring the dissemination of resistance genes.

Resistance to inhibitors of the human immunodeficiency virus type 1 integration

Brazilian 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.

The large plasmid carried class 1 integrons mediated multidrug resistance of foodborne Salmonella Indiana

Frontiers in Microbiology, 2022
Salmonella enterica serovar Indiana (S. Indiana) has aroused widespread concern as an important zoonotic pathogen. The molecular mechanism of multidrug resistance (MDR) in S. Indiana is not known and should be assessed.

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,

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 ...

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.

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.
