Escherichia coli (Migula 1895) Castellani and Chalmers 1919 (Approved Lists 1980) Brosius J. Palmer M.L. Kennedy P.J. Noller H.F. Complete nucleotide sequence of a 16S ribosomal RNA gene from Escherichia coli 1978 75 10 4801 4805 Proceedings of the National Academy of Sciences of the United States of America Proc Natl Acad Sci U S A 0027-8424 1091-6490 368799 Do not modify this record. This exemplar contains the only 16S rRNA feature that matches the Brosius 1978 sequence exactly, and does not match any named isolates. This is the sequence that was originally used for the reference points in numbering the bases. It differs from contemporary genome sequences by the deletion of a base at position 87 or 88.
