Secondary structure of 5 S ribosomal RNA.

A secondary structure model for 16S ribosomal RNA which is based on available chemical, enzymatic, and comparative sequence data shows good agreement between constraints dictated by the model and a wide variety of experimental observations. The four major structural domains created by the base-pairing scheme correspond closely to RNA fragments isolated after nuclease digestion in the presence o...

Nucleotide sequence of 5 S ribosomal RNA precursor from Bacillus subtilis.

The complete nucleotide sequence of a 179-nucleotide precursor (p5A) of 5 S ribosomal RNA from Bacillus subtilis is presented. In addition to the 116-nucleotide mature segment, the p5A molecule contains 21 additional nucleotides at its 5' end and 42 at its 3' terminus. Structural features within the p5A molecule which possibly interact with a specific maturation endonuclease (RNase M5) are ide...

Nucleotide sequence of wheat chloroplastid 4.5 S ribonucleic acid. Sequence homologies in 4.5 S RNA species.

The nucleotide sequence of wheat (Triticum aestivum L.) chloroplastid ribosome-associated 4.5 S RNA is U-A-A-G-G-U-G-A-G-C-G-G-C-G-A-G-A-C-G-A-G-C-C-G-U-U-U-A-A-A-U-A-G-G-U-G-U-C-A-A -G-U-G-G-A-A-G-U-G-C-A-G-U-G-A-U-G-U-A-U-G-C-A-G-C-U-G-A-G-G-C-A-U-C-C-U-A-A-C- G-A-A-C-G-A-A-C-G-A-U-U-U-G-A-A-COH. The sequence is highly conserved among chloroplastid 4.5 S RNAs but not related to either the 5 S...
