Estimating the fitness effect of an insertion sequence [PDF]

open access: yesJournal of Mathematical Biology, 2018
Since its discovery, mobile DNA has fascinated researchers. In particular, many researchers have debated why insertion sequences persist in prokaryote genomes and populations.

Scarless excision of an insertion sequence restores capsule production and virulence in Acinetobacter baumannii. [PDF]

open access: yesISME J, 2022
We identify a new mechanism mediating capsule production and virulence in the WHO and CDC priority ESKAPE pathogen Acinetobacter baumannii. Non-capsulated and avirulent bacteria can revert into a capsulated and virulent state upon scarless excision of an

Insertion-sequence-mediated mutations both promote and constrain evolvability during a long-term experiment with bacteria. [PDF]

open access: yesNat Commun, 2021
Insertion sequences (IS) are ubiquitous bacterial mobile genetic elements, and the mutations they cause can be deleterious, neutral, or beneficial. The long-term dynamics of IS elements and their effects on bacteria are poorly understood, including ...

Insertion sequence transposition inactivates CRISPR-Cas immunity. [PDF]

open access: yesNat Commun, 2023
AbstractCRISPR-Cas immunity systems safeguard prokaryotic genomes by inhibiting the invasion of mobile genetic elements. Here, we screened prokaryotic genomic sequences and identified multiple natural transpositions of insertion sequences (ISs) into cas genes, thus inactivating CRISPR-Cas defenses.

Insertion Sequences [PDF]

open access: yesMicrobiology and Molecular Biology Reviews, 1998
SUMMARY Insertion sequences (ISs) constitute an important component of most bacterial genomes. Over 500 individual ISs have been described in the literature to date, and many more are being discovered in the ongoing prokaryotic and eukaryotic genome-sequencing projects. The last 10 years have also seen some striking advances in

Prediction of prime editing insertion efficiencies using sequence features and DNA repair determinants

open access: yesNature Biotechnology, 2023
Most short sequences can be precisely written into a selected genomic target using prime editing; however, it remains unclear what factors govern insertion.

Insertion sequences in prokaryotic genomes [PDF]

open access: yesCurrent Opinion in Microbiology, 2006
Insertion sequences (ISs) are small DNA segments that are often capable of moving neighbouring genes. Over 1500 different ISs have been identified to date. They can have large and spectacular effects in shaping and reshuffling the bacterial genome. Recent studies have provided dramatic examples of such IS activity, including massive IS expansion during

Insertion Sequence Diversity in Archaea [PDF]

open access: yesMicrobiology and Molecular Biology Reviews, 2007
SUMMARYInsertion sequences (ISs) can constitute an important component of prokaryotic (bacterial and archaeal) genomes. Over 1,500 individual ISs are included at present in the ISfinder database (www-is.biotoul.fr), and these represent only a small portion of those in the available prokaryotic genome sequences and those that are being discovered in ...

Everyman's Guide to Bacterial Insertion Sequences [PDF]

open access: yesMicrobiology Spectrum, 2015
ABSTRACT The number and diversity of known prokaryotic insertion sequences (IS) have increased enormously since their discovery in the late 1960s. At present the sequences of more than 4000 different IS have been deposited in the specialized ISfinder database. Over time it has become increasingly apparent that they are important actors in the

Insertion Sequence IS 900 Revisited [PDF]

open access: yesJournal of Clinical Microbiology, 2006
ABSTRACT Many studies investigating Mycobacterium avium subsp. paratuberculosis in Crohn's disease have used molecular detection of IS 900 in clinical samples, but some have described polymorphisms in IS 900 as variants of this ...
