Identification of elements involved in transcriptional regulation of the Escherichia coli cad operon by external pH.
Expression of the lysine decarboxylase gene (cadA) of Escherichia coli is induced upon external acidification. To dissect the molecular mechanisms responsible for this regulation, we analyzed a 4.2-kbp region upstream from cadA. DNA sequencing revealed two long open reading frames upstream of and on the same strand as cadA. One of these, cadB, is 444 codons long and is situated immediately upst...
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 کاملGenetic analysis of the rnc operon of Escherichia coli.
RNase III, an Escherichia coli double-stranded endoribonuclease, is known to be involved in maturation of rRNA and regulation of several bacteriophage and Escherichia coli genes. Clones of the region of the E. coli chromosome containing the gene for RNase III (rnc) were obtained by screening genomic libraries in lambda with DNA known to map near rnc. A phage clone with the rnc region was random...
