Nucleotide sequence of the alpha ribosomal protein operon ofEscherichia coli

Abstract
In Escherichia coli some 19 transcription units encodinq the 52 ribosomal proteins are scattered throuqhout the qenome. One of the units, the alpha operon, encodes genes for the ribosomal proteins S13, S11, S4 and L17 as well as the alpha subunit of RNA polymerase. We report here the complete 3.0 kb nucleotide sequence of the alpha operon. In addition, we have determined by S1 nuclease mapping the site of transcription termination 1n this operon
