Abstract
Recent genomic studies with Escherichia coli K-12 have suggested scores of previously unexplored targets for the cyclic AMP receptor protein (CRP) global transcription regulator. Eleven of these loci were cloned and CRP binding was demonstrated at eight of these targets. It is shown that CRP can activate transcription at five of these targets and the functional DNA sites for CRP are identified. It is reported that CRP functions as a Class I activator at the aer promoter and as a Class II activator at the gatY, sdaC, ychH and malX promoters.
