Composite mobile genetic elements disseminating macrolide resistance in Streptococcus pneumoniae

Frontiers in Microbiology, 2015
Macrolide resistance in Streptococcus pneumoniae emerged in the US and globally during the early 1990’s. The RNA methylase encoded by erm(B) and the macrolide efflux genes mef(E) and mel were identified as the resistance determining factors.

ACLAME: A CLAssification of Mobile genetic Elements [PDF]

Nucleic Acids Research, 2004
The ACLAME database (http://aclame.ulb.ac.be) is a collection and classification of prokaryotic mobile genetic elements (MGEs) from various sources, comprising all known phage genomes, plasmids and transposons. In addition to providing information on the full genomes and genetic entities, it aims to build a comprehensive classification of the ...

Mammalian small nucleolar RNAs are mobile genetic elements. [PDF]

PLoS Genetics, 2006
Small nucleolar RNAs (snoRNAs) of the H/ACA box and C/D box categories guide the pseudouridylation and the 2'-O-ribose methylation of ribosomal RNAs by forming short duplexes with their target.

Vancomycin Resistance in Enterococcus faecium from the Dallas, Texas, Area Is Conferred Predominantly on pRUM-Like Plasmids

mSphere, 2023
Vancomycin-resistant E. faecium (VREfm) is a significant public health concern because of limited treatment options. Genomic surveillance can be used to monitor VREfm transmission and evolution.

The defense island repertoire of the Escherichia coli pan-genome.

PLoS Genetics, 2023
It has become clear in recent years that anti-phage defense systems cluster non-randomly within bacterial genomes in so-called "defense islands". Despite serving as a valuable tool for the discovery of novel defense systems, the nature and distribution ...

Mobile genetic elements – mechanism and consequences of transposition

Journal of Education, Health and Sport, 2017
Retrotransposons represent a significant part of the genome in eukaryote organisms. With DNA transposons, they belong to mobile genetic elements. There are two classes of transposons, DNA transposons and retrotransposons.

Discovery of multiple anti-CRISPRs highlights anti-defense gene clustering in mobile genetic elements

Nature Communications, 2020
Mobile genetic elements have evolved anti-CRISPR (Acr) proteins to bypass the immunity provided by prokaryotic CRISPR–Cas systems. Here, the authors identify 11 type I Acrs encoded on mobile genetic elements, and show that acr loci neighborhoods can be ...

Searching for active mobile genetic elements in dsRNA fraction of Pinus sylvestris having witches broom abnormalities

Genomics Data, 2017
The most common type of coniferous mobile genetic elements are retrotransposons. Despite of their early positive impact on evolution of modern coniferous species they can have a significant negative impact for Forestry and breeding.
