Cra-dependent transcriptional activation of the icd gene of Escherichia coli.


The icd gene of Escherichia coli, encoding isocitrate dehydrogenase, was shown to be expressed from two different promoters: the previously identified icd P1 and a newly detected second promoter, icd P2, whose expression is positively regulated by the catabolite repressor-activator protein Cra, formerly called FruR. In each case, we determined the mRNA… (More)
