The internal regulated promoter of the deo operon of Escherichia coli K- 12
Previous studies of the structure and regulation of the deo operon in Escherichia coli have localized an internal regulated promoter, called deoP3, in front of the two distal genes in the operon. We report here the nucleotide sequence of the distal portion of the deoA, the deoA-deoB intercistronic region and the first part of the deoB gene, and show that deoP3 overlaps the distal segment of the...
متن کاملCloning and expression of rhl AB operon under the control of tac promoter in E. coli
Today, efforts go towards the replacement of chemical surfactants by natural biological biosurfactants (biosurfactant), as these materials are not carcinogenic and highly compatibile with the environment. One of the main classes of biosurfactants is rhamnose containing glycolipid biosurfactant (rhamnolipids). This type of biosurfactants can be applied in many industries such as oil industry, ph...
متن کاملAntitermination by both the promoter and the leader regions of an Escherichia coli ribosomal RNA operon.
RNA polymerase initiating at Escherichia coli ribosomal RNA promoter-leader regions can efficiently read through factor rho-dependent termination signals. Dissection of the promoter-leader region reveals that the ability to read through termination signals is conferred independently by both promoter and leader regions. Events in the leader also affect the transcription rate of structural genes ...

this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
hlyM, a transcriptional silencer downstream of the promoter in the hly operon of Escherichia coli.
Transcription of the hly operon of transmissible plasmids in Escherichia coli is subject to a tight regulation which also involves various chromosomal genes, such as hha. We have identified a 200-bp region within the hlyC gene, designated hlyM, which modulates hemolysin expression. The deletion of hlyM increased the activity of hly::galK fusion 20-fold. hlyM does not contain any internal promot...
