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).

A New Freshwater Cyanosiphovirus Harboring Integrase [PDF]
Frontiers in Microbiology, 2018 Pelagic cyanobacteria are key players in the functioning of aquatic ecosystems, and their viruses (cyanophages) potentially affect the abundance and composition of cyanobacterial communities. Yet, there are few well-described freshwater cyanophages relative to their marine counterparts, and in general, few cyanosiphoviruses (family Siphoviridae) have ...

Allosteric HIV-1 integrase inhibitors lead to premature degradation of the viral RNA genome and integrase in target cells [PDF]
, 2017 Recent evidence indicates that inhibition of HIV-1 integrase (IN) binding to the viral RNA genome by allosteric integrase inhibitors (ALLINIs) or through mutations within IN yields aberrant particles in which the viral ribonucleoprotein complexes (vRNPs)

The SSV1 viral integrase is not essential
Virology, 2007 Viral integration is a widely conserved characteristic in viruses in all domains of life; however, its necessity is not well understood in many cases. Integration using tyrosine recombinases is one of the most widespread and best characterized mechanisms of integration. We completely removed the tyrosine recombinase integrase from the hyperthermophilic

Prototype Foamy Virus Integrase Displays Unique Biochemical Activities among Retroviral Integrases [PDF]
Biomolecules, 2021 Integrases of different retroviruses assemble as functional complexes with varying multimers of the protein. Retroviral integrases require a divalent metal cation to perform one-step transesterification catalysis. Tetrameric prototype foamy virus (PFV) intasomes assembled from purified integrase and viral DNA oligonucleotides were characterized for ...

Integrase-deficient lentiviral vectors mediate efficient gene transfer to human vascular smooth muscle cells with minimal genotoxic risk [PDF]
, 2012 We have previously shown that injury-induced neointima formation was rescued by adenoviral-Nogo-B gene delivery. Integrase-competent lentiviral vectors (ICLV) are efficient at gene delivery to vascular cells but present a risk of insertional mutagenesis.

Adaptive HIV-1 evolutionary trajectories are constrained by protein stability [PDF]
, 2017 Despite the use of combination antiretroviral drugs for the treatment of HIV-1 infection, the emergence of drug resistance remains a problem. Resistance may be conferred either by a single mutation or a concerted set of mutations.

Lambda Integrase: Armed for Recombination [PDF]
Current Biology, 2005 Bacteriophage lambda moves its viral genome into and out of the bacterial chromosome using site-specific recombination. Crystal structures of reaction intermediates in this recombination pathway provide exciting new snapshots of full length lambda integrase interacting with both core and regulatory DNA elements.
