Mobile genetic elements

Challacombe J, Kuske C.
PMID: 23087842
Mob Genet Elements. 2012 Jul 01;2(4):179-183. doi: 10.4161/mge.21943.

Analysis of the genome of Candidatus Solibacter usitatus Ellin6076, a member of the phylum Acidobacteria, revealed a large number of genes associated with mobile genetic elements. These genes encoded transposases, insertion sequence elements and phage integrases. When the amino...

Serine integrase chimeras with activity in E. coli and HeLa cells.

Biology open

Farruggio AP, Calos MP.
PMID: 25217617
Biol Open. 2014 Sep 12;3(10):895-903. doi: 10.1242/bio.20148748.

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 integration and cassette exchange in a...

Bracoviruses recruit host integrases for their integration into caterpillar's genome.

PLoS genetics

Wang Z, Ye X, Zhou Y, Wu X, Hu R, Zhu J, Chen T, Huguet E, Shi M, Drezen JM, Huang J, Chen X.
PMID: 34492000
PLoS Genet. 2021 Sep 07;17(9):e1009751. doi: 10.1371/journal.pgen.1009751. eCollection 2021 Sep.

Some DNA viruses infect host animals usually by integrating their DNAs into the host genome. However, the mechanisms for integration remain largely unknown. Here, we find that Cotesia vestalis bracovirus (CvBV), a polydnavirus of the parasitic wasp C. vestalis...

Prototype Foamy Virus Integrase Displays Unique Biochemical Activities among Retroviral Integrases.

Biomolecules

Rabe AJ, Tan YY, Larue RC, Yoder KE.
PMID: 34944553
Biomolecules. 2021 Dec 20;11(12). doi: 10.3390/biom11121910.

Integrases of different retroviruses assemble as functional complexes with varying multimers of the protein. Retroviral integrases require a divalent metal cation to perform one-step transesterification catalysis. Tetrameric prototype foamy virus (PFV) intasomes assembled from purified integrase and viral DNA...

HIV-1 group O integrase displays lower susceptibility to raltegravir and has a different mutational pathway for resistance than HIV-1 group M.

Journal of the International AIDS Society

Depatureaux A, Mesplède T, Quashie P, Oliveira M, Moisi D, Brenner B, Wainberg M.
PMID: 25397483
J Int AIDS Soc. 2014 Nov 02;17(4):19738. doi: 10.7448/IAS.17.4.19738. eCollection 2014.

INTRODUCTION: HIV-1 group O (HIV-O) is a rare HIV-1 variant characterized by a high number of polymorphisms, especially in the integrase gene, e.g. positions L74I, S153A, G163Q and T206S. As HIV-O integrase enzymes have not previously been studied, our...

Positioning Diverse Type IV Structures and Functions Within Class 1 CRISPR-Cas Systems.

Frontiers in microbiology

Taylor HN, Laderman E, Armbrust M, Hallmark T, Keiser D, Bondy-Denomy J, Jackson RN.
PMID: 34093491
Front Microbiol. 2021 May 21;12:671522. doi: 10.3389/fmicb.2021.671522. eCollection 2021.

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 CRISPR systems has made it...

Cellular Immune Response Induced by DNA Immunization of Mice with Drug Resistant Integrases of HIV-1 Clade A Offers Partial Protection against Growth and Metastatic Activity of Integrase-Expressing Adenocarcinoma Cells.

Microorganisms

Isaguliants M, Krotova O, Petkov S, Jansons J, Bayurova E, Mezale D, Fridrihsone I, Kilpelainen A, Podschwadt P, Agapkina Y, Smirnova O, Kostic L, Saleem M, Latyshev O, Eliseeva O, Malkova A, Gorodnicheva T, Wahren B, Gordeychuk I, Starodubova E, Latanova A.
PMID: 34199989
Microorganisms. 2021 Jun 04;9(6). doi: 10.3390/microorganisms9061219.

Therapeutic DNA-vaccination against drug-resistant HIV-1 may hinder emergence and spread of drug-resistant HIV-1, allowing for longer successful antiretroviral treatment (ART) up-to relief of ART. We designed DNA-vaccines against drug-resistant HIV-1 based on consensus clade A integrase (IN) resistant to...

Contribution of plasmidome, metal resistome and integrases to the persistence of the antibiotic resistome in aquatic environments.

Environmental pollution (Barking, Essex : 1987)

Di Cesare A, Sabatino R, Yang Y, Brambilla D, Li P, Fontaneto D, Eckert EM, Corno G.
PMID: 34974089

Wastewater treatment plants (WWTPs) are among the main hotspots of antibiotic resistance genes (ARGs) in the environment. Previously, we demonstrated that, by increasing anthropogenic pollution, the antibiotic resistome persisted in the microbial community of rivers and lakes, independently by...
