Promoter-probe and terminator-probe plasmid vectors make possible to rapidly examine whether particular sequences function as promoter or terminator signals in various genetic backgrounds and under diverse environmental stimuli. At present, such plasmid-based genetic tools are very scarce in the Gram-positive pathogenic bacteria Streptococcus pneumoniae and(More)
Enterococcus faecalis is a natural inhabitant of the human gastrointestinal tract. However, as an opportunistic pathogen, it is able to colonize other host niches and cause life-threatening infections. Its adaptation to new environments involves global changes in gene expression. The EF3013 gene (here named mafR) of E. faecalis strain V583 encodes a protein(More)
