Retroviral integration into nucleosomes through DNA looping and sliding along the histone octamer

open access: yesNature Communications, 2019
Retroviral integrases catalyze the insertion of viral DNA into the host cell DNA and can use nucleosomes as substrates for integration. Here the authors present the 3.9 Å cryo-EM structure of prototype foamy virus integrase after strand transfer into ...

Unraveling the genomic mosaic of a ubiquitous genus of marine cyanobacteria [PDF]

open access: yes, 2008
Background: The picocyanobacterial genus Synechococcus occurs over wide oceanic expanses, having colonized most available niches in the photic zone. Large scale distribution patterns of the different Synechococcus clades (based on 16S rRNA gene markers)

Metagenomic community composition and resistome analysis in a full-scale cold climate wastewater treatment plant

open access: yesEnvironmental Microbiome, 2022
Background Wastewater treatment plants are an essential part of maintaining the health and safety of the general public. However, they are also an anthropogenic source of antibiotic resistance genes.

Bacterial transposases and retroviral integrases [PDF]

open access: yesMolecular Microbiology, 1995
SummaryTransposable genetic elements have adopted two major strategies for their displacement from one site to another within and between genomes. One involves passage through an RNA intermediate prior to synthesis of a DNA copy while the other is limited uniquely to DNA intermediates.

Genome integration and excision by a new Streptomyces bacteriophage, ϕJoe [PDF]

open access: yes, 2017
Bacteriophages are the source of many valuable tools for molecular biology and genetic manipulation. In Streptomyces, most DNA cloning vectors are based on serine integrase site-specific DNA recombination systems derived from phage.

Mechanistic modelling of a recombinase-based two-input temporal logic gate [PDF]

open access: yes, 2017
Site-specific recombinases (SSRs) mediate efficient manipulation of DNA sequences in vitro and in vivo. In particular, serine integrases have been identified as highly effective tools for facilitating DNA inversion, enabling the design of genetic ...

Genomic and Functional Characterization of Vancomycin-Resistant Enterococci-Specific Bacteriophages in the Galleria mellonella Wax Moth Larvae Model

open access: yesPharmaceutics, 2022
Phages are naturally occurring viruses that selectively kill bacterial species without disturbing the individual’s normal flora, averting the collateral damage of antimicrobial usage.

The role of single occupancy effects on integrase dynamics in a cell-free system [PDF]

open access: yes, 2016
Phage integrase-based circuits are an alternative approach to relying on transcriptional and translational repression for biomolecular circuits. Previous research has shown that circuits based on integrases can perform a variety of functions, including ...

Delivery of Islatravir via High Drug‐Load, Long‐acting Microarray Patches for the Prevention or Treatment of Human Immunodeficiency Virus

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
Islatravir‐loaded dissolving microarray patches (MAPs) provide a minimally invasive, long‐acting solution for HIV‐1 prevention and treatment. In rats, sustained islatravir delivery lasts up to three months, while in minipigs, efficacious plasma levels are detected for six days.

Multiple choices for HIV therapy with integrase strand transfer inhibitors

open access: yesRetrovirology, 2012
Two integrases inhibitors, raltegravir and elvitegravir, have now been approved by regulatory agencies for use in the treatment of HIV-infected patients; and the approval of a third such drug, dolutegravir, is expected during 2013 on the basis of several
