The 16S ribosomal RNA mutation database (16SMDB)
The 16S ribosomal RNA mutation database (16SMDB) provides a list of mutated positions in 16S ribosomal RNA from Escherichia coli and the identity of each alteration. Information provided for each mutation includes: (i) a brief description of the phenotype(s) associated with each mutation; (ii) whether a mutant phenotype has been detected by in vivo or in vitro methods; (iii) relevant literature...
متن کاملAptazyme-mediated regulation of 16S ribosomal RNA.
Developing artificial genetic switches in order to control gene expression via an external stimulus is an important aim in chemical and synthetic biology. Here, we expand the application range of RNA switches to the regulation of 16S rRNA function in Escherichia coli. For this purpose, we incorporated hammerhead ribozymes at several positions into orthogonalized 16S rRNA. We observed that ribos...
متن کاملLocation of ribosomal protein binding sites on 16S ribosomal RNA.
The distribution of ribosomal protein binding sites on the 16S ribosomal RNA molecule has been analyzed by limited ribonuclease hydrolysis of RNA-protein complexes, as well as by the interaction of individual proteins with RNA fragments purified from partial enzymatic digests. Of the six 30S subunit proteins known to interact directly with 16S RNA, proteins S4, S8, S15, S20, and, probably, S13 ...
متن کاملRapid determination of 16S ribosomal RNA sequences for phylogenetic analyses.
Although the applicability of small subunit ribosomal RNA (16S rRNA) sequences for bacterial classification is now well accepted, the general use of these molecules has been hindered by the technical difficulty of obtaining their sequences. A protocol is described for rapidly generating large blocks of 16S rRNA sequence data without isolation of the 16S rRNA or cloning of its gene. The 16S rRNA...
متن کاملPhylogenetic evidence for tertiary interactions in 16S-like ribosomal RNA.
Major efforts are underway to elucidate the spatial distribution of ribosomal RNAs (rRNAs) in the ribosome. An especially informative approach is the identification of likely base-base tertiary interactions within the RNA by phylogenetic comparison. Herein evidence is presented for three heretofore unrecognized candidate tertiary interactions, G506/C525, C779/G803 and A994/U1380 (1) in 16S-like...
