Abstract excerpt
Transcription of the mal regulon of Escherichia coli K-12 is regulated by the positive activator, MalT. In the presence of ATP and maltotriose, MalT binds to decanucleotide MalT boxes that are found upstream of mal promoters and activates transcription at these sites. The earliest studies of the...
