Expanded versions of the 16S and 23S ribosomal RNA mutation databases (16SMDBexp and 23SMDBexp)

Expanded versions of the Ribosomal RNA Mutation Databases provide lists of mutated positions in 16S and 16S-like ribosomal RNA (16SMDBexp) and 23S and 23S-like ribosomal RNA (23SMDBexp) and the identity of each alteration. Alterations from organisms other than Escherichia coli are reported at positions according to the E.coli numbering system. 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, and (iii) relevant literature citations. The databases are available via ftp and on the World Wide Web at the following URL: http: //www.fandm.edu/Departments/Biology/Databases/RNA.h tml

Expansion of the 16S and 23S ribosomal RNA mutation databases (16SMDB and 23SMDB).

The Ribosomal RNA Mutation Databases (16SMDB and 23SMDB) provide lists of mutated positions in 16S and 23S 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; and (iii) relevant literature citations. The databases are available via ftp and on the World Wide Web. Expansion of the databases to include information about mutations isolated in organisms other than E.coli is currently in progress.

Growth properties associated with A-U replacement of specific G-C base pairs in 16S rRNA from Escherichia coli.

Mutations that disrupt each of seven specific G-C base pairs in 16S rRNA from Escherichia coli confer loss of expression of a plasmid-encoded 16S rRNA selectable marker (spectinomycin resistance). However, A-U replacement of G-C base pairs at nucleotides 359/52 or 1292/1245 in 16S rRNA permits normal expression of the marker. By contrast, A-U replacements at 146/176, 153/168, 350/339, or 1293/1244 are associated with loss of expression of the marker. These genetic studies are designed to determine the importance of specific base pairs by assessment of the structural and functional impairments of 16S rRNA molecules resulting from expression of base pair substitutions at these positions.

Structure of chi hotspots of generalized recombination.

Chi recombinational hotspots are sites around which the rate of Rec-promoted recombination in bacteriophage lambda is elevated. Examination of a derivative of lambda into which the plasmid pBR322 was inserted reveals that pBR322 lacks Chi sites. Using this lambda-pBR322 hybrid, we obtained mutations creating Chi sites at three widely separated loci within pBR322. Nucleotide sequence analysis reveals that the mutations are single base-pair changes creating the octamer 5' GCTGGTGG 3'. This sequence is present at three previously analyzed Chi sites in lambda, and all analyzed mutations creating or inactivating these Chi sites occur within this octamer. We conclude that Chi is 5' GCTGGTGG 3', or its complement, or both.
