Tetracyclines possess many properties considered ideal for antibiotic drugs, including
activity against Gram-positive and-negative pathogens, proven clinical safety, acceptable …

Transposable elements (TE), small mobile genetic elements unable to exist independently
of the host genome, were initially believed to be exclusively deleterious genomic parasites …

SUMMARY A substantial amount of antisense transcription is a hallmark of gene expression
in eukaryotes. However, antisense transcription was first demonstrated in bacteria almost 50 …

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 …

We have divided this review into two major sections. In one, we have attempted to present
an overview of our current understanding of prokaryotic insertion sequences (IS), their …

The origin and mobilization of the~ 2,609-bp DNA segment containing the mobile colistin
resistance gene mcr-1 continue to be sources of uncertainty, but recent evidence suggests …

Insertion sequences (ISs) are the smallest and most frequent transposable elements in
prokaryotes where they play an important evolutionary role by promoting gene inactivation …

Methanosarcina mazei and related mesophilic archaea are the only organisms fermenting
acetate, methylamines, and methanol to methane and carbon dioxide, contributing …

ABSTRACT IS Ecp1B has been reported to be associated with and to mobilize the emerging
expanded-spectrum β-lactamase bla CTX-M genes in Enterobacteriaceae. Thus, the ability …

The origin of RNA interference (RNAi) is usually explained by a defense-based hypothesis,
in which RNAi evolved as a defense against transposable elements (TEs) and RNA viruses …
