The nucleotide sequence of a 250-base pair segment of L-arabinose operon DNA containing the 150-base pair regulatory region has been determined. This segment includes the promoter for rightward araBAD transcription, pBAD, the promoter for leftward araC transcription, pC, and sites responsible for repression.
