Model for the three-dimensional folding of 16 S ribosomal RNA
Journal of Molecular Biology, 1988We have derived a model for the three-dimensional folding of Escherichia coli 16 S ribosomal RNA, using interactive computer graphic methods. It is based on (1) the secondary structure derived from comparative sequence analysis, (2) the three-dimensional co-ordinates for the centers of mass of the 30 S subunit proteins, and (3) the locations of sites ...

To Knot or Not to Knot? Examination of 16S Ribosomal RNA Models
Journal of Biomolecular Structure and Dynamics, 1998The presence of topological knots in large RNA structures is highly unlikely given that 1) no RNA structures determined thus far contain topological knots, 2) secondary structure maps for most RNA molecules are knot free, 3) there are no known RNA topoisomerases, and 4) it is difficult to imagine how knots could be formed specifically and uniquely ...

Complementary binding of oligonucleotides with 16S RNA and ribosomal ribonucleoproteins
Molecular Biology Reports, 1975The accessibility of single-stranded sequences in 16S RNA in free state and in ribonucleoprotein particles (RNP) to complementary binding with isoplith fractions of oligonucleotides was studied. RNP had different protein composition and corresponded to intermediate stages of E. coli 30S subunit assembly in vitro.

Methylation of 16S RNA during ribosome assembly in vitro
Nature, 1974Methyl deficient 16S RNA from kasugamycin resistant Escherichia coli has been used to study methylation of RNA during ribosome assembly in vitro. Methylation occurs at an intermediate stage and is inhibited at a late stage of assembly. 30S ribosomal proteins required for methylation, and inhibition, have been identified.

Images of 16S ribosomal RNA by scanning tunnelling microscopy
Journal of Microscopy, 1991SUMMARYWe report the use of scanning tunnelling microscopy (STM) to study surface topographies of complex nucleic acid structures. From low‐resolution STM images of uncoated 16S ribosomal RNA, we demonstrate the possibility of determining several objective parameters (molecular mass and radius of gyration) in order to characterize and identify the ...

3 16 S Ribosomal RNA Oligonucleotide Cataloguing
1985Publisher Summary This chapter discusses 16 S ribosomal ribonucleic acid (RNA) oligonucleotide cataloguing. 16 S ribosomal RNA is currently the subject of intense study. As a major component of the small ribosomal subunit, elucidation of 16 S rRNA secondary and tertiary structures is a key objective in the ongoing efforts to understand the structure ...

Biochemistry, 1989
16S ribosomal RNA was made by in vitro transcription of a cloned gene, and its structure was compared to authentic 16S ribosomal RNA. The comparison was made by subjecting the two types of 16S rRNA to chemical reagents that react specifically with unpaired bases and determining the extent of reaction by reverse transcription and gel electrophoresis of ...
