The DNA sequence of the gene rpsA of Escherichia coli coding for ribosomal protein S1.

The DNA sequence of the gene rpsA as well as of its neighboring regions has been determined using the dideoxyribonucleotide method. It was found that there is an "open-reading-frame" of 350 bp which precedes the gene rpsA. Furthermore, an extensive internal repeats of nucleotide sequence have been found in this gene.
