Ribonucleases (RNases) are mediators in most reactions of RNA metabolism. In recent
years, there has been a surge of new information about RNases and the roles they play in …

Although homologous recombination and DNA repair phenomena in bacteria were initially
extensively studied without regard to any relationship between the two, it is now appreciated …

Genetic interference mediated by double-stranded RNA (RNAi) has been a valuable tool in
the analysis of gene function in Caenorhabditis elegans. Here we report an efficient …

A recombination system has been developed for efficient chromosome engineering in
Escherichia coli by using electroporated linear DNA. A defective λ prophage supplies …

The Cas9-crRNA complex of the Streptococcus thermophilus DGCC7710 CRISPR3-Cas
system functions as an RNA-guided endonuclease with crRNA-directed target sequence …

RyhB is a small antisense regulatory RNA that is repressed by the Fur repressor and
negatively regulates at least six mRNAs encoding Fe-binding or Fe-storage proteins in …

The RecA protein is a recombinase functioning in recombinational DNA repair in bacteria.
RecA is regulated at many levels. The expression of the recA gene is regulated within the …

Members of the large superclass of P-loop GTPases share a core domain with a conserved
three-dimensional structure. In eukaryotes, these proteins are implicated in various crucial …

Abstract Background: Aquifex aeolicus Ribonuclease III (Aa-RNase III) belongs to the family
of Mg 2+-dependent endonucleases that show specificity for double-stranded RNA (dsRNA) …

Only few small, regulatory RNAs encoded opposite another gene have been identified in
bacteria. Here, we report the characterization of a locus where a small RNA (SymR) is …
