RAG-1 Mutations Associated with B-Cell-Negative SCID Dissociate the Nicking and Transesterification Steps of V(D)J Recombination [PDF]

open access: yes, 2001
Some patients with B-cell-negative severe combined immune deficiency (SCID) carry mutations in RAG-1 or RAG-2 that impair V(D)J recombination. Two recessive RAG-1 mutations responsible for B-cell-negative SCID, R621H and E719K, impair V(D)J recombination

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 ...

Influence of the amino-terminal sequence on the structure and function of HIV integrase

open access: yesRetrovirology, 2020
Background Antiretroviral therapy (ART) can mitigate the morbidity and mortality caused by the human immunodeficiency virus (HIV). Successful development of ART can be accelerated by accurate structural and biochemical data on targets and their responses

Control of serine integrase recombination directionality by fusion with the directionality factor [PDF]

open access: yes, 2017
Bacteriophage serine integrases are extensively used in biotechnology and synthetic biology for assembly and rearrangement of DNA sequences. Serine integrases promote recombination between two different DNA sites, attP and attB, to form recombinant attL ...

Mobile resistome of human gut and pathogen drives anthropogenic bloom of antibiotic resistance [PDF]

open access: yes, 2020
BACKGROUND:The impact of human activities on the environmental resistome has been documented in many studies, but there remains the controversial question of whether the increased antibiotic resistance observed in anthropogenically impacted environments ...

A snapshot on HIV-1 evolution through the identification of phylogenetic-specific properties of HIV-1 integrases M/O

open access: yesPLoS Pathogens, 2023
Transmissions of simian viruses to humans has originated the different groups of HIV-1. We recently identified a functional motif (CLA), in the C-terminal domain of the integrase, essential for integration in HIV-1 group M.

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.

Repressing Integrase attachment site operation with CRISPR-Cas9 in E. coli [PDF]

open access: yes, 2017
Serine integrases are bacteriophage proteins responsible for integrating the phage genome into that of the host. Synthetic biologists have co-opted these proteins into useful tools for permanent DNA logic, utilizing their specific DNA recombination ...
