In this study, we searched for integrative conjugative elements (ICEs) in chromosomes of 124 strains of Streptococci. These exhaustive analyses revealed 105 putative ICEs and 26 slightly decayed elements that were grouped in 7 distinct families ...

Directed DNA shuffling of retrovirus and retrotransposon integrase protein domains. [PDF]
Chimeric proteins are used to study protein domain functions and to recombine protein domains for novel or optimal functions. We used a library of chimeric integrase proteins to study DNA integration specificity.

Positioning Diverse Type IV Structures and Functions Within Class 1 CRISPR-Cas Systems
Type IV CRISPR systems encode CRISPR associated (Cas)-like proteins that combine with small RNAs to form multi-subunit ribonucleoprotein complexes. However, the lack of Cas nucleases, integrases, and other genetic features commonly observed in most ...

Pervasive Suicidal Integrases in Deep-Sea Archaea
Mobile genetic elements (MGEs) often encode integrases which catalyze the site-specific insertion of their genetic information into the host genome and the reverse reaction of excision.

A trade-off between the fitness cost of functional integrases and long-term stability of integrons.
Horizontal gene transfer (HGT) plays a major role in bacterial microevolution as evident from the rapid emergence and spread of antimicrobial drug resistance.

A population‐based temporal logic gate for timing and recording chemical events
Engineered bacterial sensors have potential applications in human health monitoring, environmental chemical detection, and materials biosynthesis. While such bacterial devices have long been engineered to differentiate between combinations of inputs ...

Serine integrase chimeras with activity in E. coli and HeLa cells
In recent years, application of serine integrases for genomic engineering has increased in popularity. The factor-independence and unidirectionality of these large serine recombinases makes them well suited for reactions such as site-directed vector ...

Serine Integrases: Advancing Synthetic Biology.
Serine integrases catalyze precise rearrangement of DNA through site-specific recombination of small sequences of DNA called attachment (att) sites. Unlike other site-specific recombinases, the recombination reaction driven by serine integrases is highly

Integrating vectors for genetic studies in the rare Actinomycete Amycolatopsis marina
Background Few natural product pathways from rare Actinomycetes have been studied due to the difficulty in applying molecular approaches in these genetically intractable organisms.

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