Location 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 کاملLocation and characteristics of ribosomal protein binding sites in the 16S RNA of Escherichia coli.
Specific binding sites for five proteins of the Escherichia coli 30S ribosomal subunit have been located within the 16S RNA. The sites are structurally diverse and range in size from 40 to 500 nucleotides; their functional integrity appears to depend upon both the secondary structure and conformation of the RNA molecule. Evidence is presented which indicates that additional proteins interact wi...
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 کاملStudies on the RNA and protein binding sites of the E . coli ribosomal protein LIO
We have used modification of specific amino acid residues in the E. coli ribosomal protein LIO as a tool to study its interactions with another ribosomal protein, L7/L12, as well as with ribosomal core particles and with 23S RNA. The ribosome and RNA binding capability of LIO was found to be inhibited by modification of one more more of its arginine residues. This treatment does not affect the ...
متن کاملThe 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...
