An experimentally-derived model for the secondary structure of the 16S ribosomal RNA from Escherichia coli.

AUTOR(ES)
RESUMO

Ribonucleoprotein fragments are isolated by mild ribonuclease digestion of E. coli 30S ribosomal subunits, and are deproteinized and subjected to a second partial digestion. Base-pairing between the resulting small RNA fragments is investigated using the two-dimensional gel electrophoresis procedure already reported (see Ref. 1). The interactions thus found are incorporated into a secondary structure model covering approximately 80% of the 16S RNA.
