Degradation of Escherichia coli uncB mRNA by multiple endonucleolytic cleavages.
The mechanism of segmental decay of the uncB sequence near the 5' end of the 7-kb Escherichia coli unc operon mRNA was investigated. Northern (RNA) blots of mRNA expressed from a plasmid carrying the uncBE portion of the operon revealed that the uncB message was rapidly degraded by multiple internal cleavages which resulted in the formation of at least five discrete species having a common 3' e...
متن کاملAzaserine resistance in Escherichia coli: chromosomal location of multiple genes.
Resistance to azaserine in Escherichia coli is the result of mutations in at least three different loci. All spontaneously arising azaserine-resistant mutants harbor a lesion in the aroP gene. However, a lesion in this gene is not solely responsible for resistance. All spontaneously arising intermediate-level azaserine-resistant mutants also harbor a lesion in a gene designated azaA, which lies...

متن کاملThe degA gene product accelerates degradation of Bacillus subtilis phosphoribosylpyrophosphate amidotransferase in Escherichia coli.
A search for genes involved in the inactivation and degradation of enzymes in sporulating Bacillus subtilis led to identification of the B. subtilis degA gene, whose product stimulates degradation of B. subtilis glutamine phosphoribosylpyrophosphate amidotransferase in Escherichia coli cells. degA encodes a 36.7-kDa protein that has sequence similarity to several E. coli and B. subtilis regulat...
متن کاملDetection of Colicin genes by PCR in Escherichia coli isolated from cattle in Shiraz-Iran
A variety of probiotic bacteria have been tested to control animal and foodborne pathogenic bacteria in livestock. The mechanism of inhibition of pathogenic bacteria for several of those probiotic microorganisms is mediated by the production of bacteriocins. Colicins are probably the group of bacteriocins that have been most thoroughly characterized. Colicins are antimicrobial proteins produced...
