Targeted Conservative Cointegrate Formation Mediated by IS26 Family Members Requires Sequence Identity at the Reacting End

CJ Harmer, RM Hall - Msphere, 2021 - Am Soc Microbiol
ABSTRACT IS 26 forms cointegrates using two distinct routes, a copy-in mechanism
involving one insertion sequence (IS) and a target and a targeted conservative mechanism …

IS26 Family Members IS257 and IS1216 Also Form Cointegrates by Copy-In and Targeted Conservative Routes

CJ Harmer, RM Hall - Msphere, 2020 - Am Soc Microbiol
ABSTRACT IS 26 has been shown to form cointegrates both by a copy-in mechanism
involving one insertion sequence (IS) and a target and by a targeted conservative …

Movement of IS 26-associated antibiotic resistance genes occurs via a translocatable unit that includes a single IS 26 and preferentially inserts adjacent to another IS …

CJ Harmer, RA Moran, RM Hall - MBio, 2014 - Am Soc Microbiol
The insertion sequence IS 26 plays a key role in disseminating antibiotic resistance genes in
Gram-negative bacteria, forming regions containing more than one antibiotic resistance …

Transposase and cointegrase: specialized transposition proteins of the bacterial insertion sequence IS21 and related elements

B Berger, D Haas - Cellular and Molecular Life Sciences CMLS, 2001 - Springer
The bacterial insertion sequence IS 21 shares with many insertion sequences a two-step,

[HTML][HTML] The dynamic network of IS30 transposition pathways

F Olasz, M Szabó, A Veress, M Bibó, J Kiss - Plos one, 2022 - journals.plos.org
The E. coli element IS 30 has adopted the copy-out-paste-in transposition mechanism that is
prevalent in a number of IS-families. As an initial step, IS 30 forms free circular transposition …

IS26 and the IS26 family: versatile resistance gene movers and genome reorganizers

CJ Harmer, RM Hall - Microbiology and Molecular Biology …, 2024 - Am Soc Microbiol
In Gram-negative bacteria, the insertion sequence IS 26 is highly active in disseminating
antibiotic resistance genes. IS 26 can recruit a gene or group of genes into the mobile gene …

Targeted conservative formation of cointegrates between two DNA molecules containing IS26 occurs via strand exchange at either IS end

CJ Harmer, RM Hall - Molecular Microbiology, 2017 - Wiley Online Library
We recently proposed a model for targeted, conservative cointegrate formation between
DNA molecules each containing a copy of IS26, that involves Tnp26‐catalyzed strand …

[HTML][HTML] The IS6 family, a clinically important group of insertion sequences including IS26

A Varani, S He, P Siguier, K Ross, M Chandler - Mobile Dna, 2021 - Springer
The IS 6 family of bacterial and archaeal insertion sequences, first identified in the early
1980s, has proved to be instrumental in the rearrangement and spread of multiple antibiotic …

Cointegrase, a naturally occurring, truncated form of IS21 transposase, catalyzes replicon fusion rather than simple insertion of IS21

S Schmid, T Seitz, D Haas - Journal of molecular biology, 1998 - Elsevier
The bacterial insertion sequence IS21 contains two genes, istA and istB, which are
organized as an operon. IS21 spontaneously forms tandem repeats designated (IS21) 2 …

[HTML][HTML] Characterization of the specific DNA-binding properties of Tnp26, the transposase of insertion sequence IS26

CH Pong, CJ Harmer, JK Flores, SF Ataide… - Journal of Biological …, 2021 - ASBMB
The bacterial insertion sequence (IS) IS26 mobilizes and disseminates antibiotic resistance
genes. It differs from bacterial IS that have been studied to date as it exclusively forms …
