L-arabinose operon of Escherichia coli
TIG December 2000, volume 16, No. 12 559 Over forty years of research on the L-arabinose operon of Escherichia coli have provided insights into the mechanism of positive regulation of gene activity. This research also discovered DNA looping and the mechanism by which the regulatory protein changes its DNA-binding properties in response to the presence of arabinose. As is frequently seen in focu...
متن کاملGenetic analysis of the histidine operon in Escherichia coli K12.
I N Salmonella typhimurium a cluster of nine genes, behaving as a single operon (AMES and GARRY 1959) specify the enzymes which carry out the ten reactions involved in the biosynthesis of histidine; one of the nine enzymes is bifunctional (LOPER, GRABNAR, STAHL, HARTMAN and HARTMAN 1964). The histidine operon is contained in a linear segment of deoxyribonucleic acid (DNA) estimated by AMES, GOL...
متن کاملThe dinB operon and spontaneous mutation in Escherichia coli.
Apparently conflicting data regarding the role of SOS-inducible, error-prone DNA polymerase IV (DinB) in spontaneous mutation are resolved by the finding that mutation is reduced by a polar allele with which dinB and neighboring yafN are deleted but not by two nonpolar dinB alleles. We demonstrate the existence of a dinB operon that contains four genes, dinB-yafN-yafO-yafP. The results imply a ...
متن کاملRegulation of the L-arabinose operon in Escherichia coli
GENERAL BACKGROUND Escherichia coli can grow on L-arabinose as a source of carbon and energy (Fig. 1) (Schleif, 1996). Not surprisingly, because the amounts of enzymes required to convert arabinose into a component of the pentose phosphate shunt are significant, the levels of the enzymes are regulated. In the absence of arabinose, the uninduced or basal level of expression of the proteins is ab...
متن کاملIn vitro expression of the Escherichia coli nusA-infB operon.
The expression of the nusA-infB operon has been investigated using an in vitro system based on the formation of the first dipeptide of the gene product. A series of plasmids containing various deletions of the operon were used as templates in this study. Of the four genes coding for protein products, 15Ka, nusA, infB, and 15Kb, only 15Ka was not expressed in this dipeptide system. The initial d...
