title: Probing the structure of 16 S ribosomal RNA from Bacillus brevis.
abstract: A majority (approximately 89%) of the nucleotide sequence of Bacillus brevis 16 S rRNA has been determined by a combination of RNA sequencing methods. Several experimental approaches have been used to probe its structure, including (a) partial RNase digestion of 30 S ribosomal subunits, followed by two-dimensional native/denatured gel electrophoresis, in which base-paired fragments were directly identified; (b) identification of positions susceptible to cleavage by RNase A and RNase T1 in 30 S subunits; (c) sites of attack by cobra venom RNase on naked 16 S rRNA; and (d) nucleotides susceptible to attack by bisulfite in 16 S rRNA. These data are discussed with respect to a secondary structure model for B. brevis 16 S rRNA derived by comparative sequence analysis.
