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.

Substrate specificity of Ty1 integrase [PDF]
Journal of Virology, 1995 Integration of the Saccharomyces cerevisiae retrotransposon Ty1 requires the element-encoded integrase (IN) protein, which is a component of cytoplasmic virus-like particles (VLPs). Using purified recombinant Ty1 IN and an oligonucleotide integration assay based on Ty1 long terminal repeat sequences, we have compared IN activity on substrates having ...

Structure and function of retroviral integrase [PDF]
Nature Reviews Microbiology, 2021 A hallmark of retroviral replication is establishment of the proviral state, wherein a DNA copy of the viral RNA genome is stably incorporated into a host cell chromosome. Integrase is the viral enzyme responsible for the catalytic steps involved in this process, and integrase strand transfer inhibitors are widely used to treat people living with HIV ...

Retroviral integrases and their cousins [PDF]
Current Opinion in Structural Biology, 1996 The recently determined structures of the catalytic domains of HIV integrase, avian sarcoma virus integrase and the Mu transposase are strikingly similar to each other and also exhibit significant similarity to several nucleases. All these enzymes of cut polynucleotides, leaving 3'OH and 5'PO4 groups. The integrase and transposase also possess a strand-

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.

Resistance to Integrase Inhibitors [PDF]
Viruses, 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]
Proceedings 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 ...

Retroviral Integrase: Then and Now [PDF]
Annual 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

A Robust and Accurate Filter Paper-Based Dried Plasma Spot Method for Bictegravir Monitoring in HIV Therapy. [PDF]
Rapid Commun Mass SpectromABSTRACT Context Therapeutic drug monitoring (TDM) involves the collection of biological samples such as blood, plasma, urine, and saliva. The most commonly used biological matrix for the detection of drugs is either blood or plasma, as they are widely accepted by the regulatory authorities.

New Applications for Phage Integrases [PDF]
Journal of Molecular Biology, 2014 Within the last 25 years, bacteriophage integrases have rapidly risen to prominence as genetic tools for a wide range of applications from basic cloning to genome engineering. Serine integrases such as that from ϕC31 and its relatives have found an especially wide range of applications within diverse micro-organisms right through to multi-cellular ...
