title: Transcriptional organization of the rpsA operon of Escherichia coli.
abstract: Three strong and two minor rpsA promoters were found by nuclease S1 mapping, promoter cloning and in vitro transcription. The longest transcript encodes a protein, located upstream from rpsA with a molecular weight of 25,000. The identity of this protein remains to be established. The other rpsA promoters are located within the gene for this 25 K protein. The rpsA leader region including the sequence of the 25 K protein and its promoter was DNA sequenced.
