Escherichia coli cells bearing a ribosomal ambiguity mutation in rpsD have a mutator phenotype that correlates with increased mistranslation.

چکیده
Escherichia coli cells bearing certain mutations in rpsD (coding for the 30S ribosomal protein S4) show a ribosomal ambiguity (Ram) phenotype characterized by increased translational error rates. Here we show that spontaneous mutagenesis increases in Ram cells bearing the rpsD14 allele, suggesting that the recently described translational stress-induced mutagenesis pathway is activated in Ram cells.

Escherichia coli cells expressing a mutant glyV (glycine tRNA) gene have a UVM-constitutive phenotype: implications for mechanisms underlying the mutA or mutC mutator effect.
Transfection of M13 single-stranded viral DNA bearing a 3,N4-ethenocytosine lesion into Escherichia coli cells pretreated with UV results in a significant elevation of mutagenesis at the lesion site compared to that observed in untreated cells. This response, termed UVM, for UV modulation of mutagenesis, is induced by a variety of DNA-damaging agents and is distinct from known cellular response...
متن کاملThe rpsD gene, encoding ribosomal protein S4, is autogenously regulated in Bacillus subtilis.
Although the mechanisms for regulation of ribosomal protein gene expression have been established for gram-negative bacteria such as Escherichia coli, the regulation of these genes in gram-positive bacteria such as Bacillus subtilis has not yet been characterized. In this study, the B. subtilis rpsD gene, encoding ribosomal protein S4, was found to be subject to autogenous control. In E. coli, ...
متن کاملMutator natural Escherichia coli isolates have an unusual virulence phenotype.
A small percentage of natural Escherichia coli isolates (both commensal and pathogenic) have a mutator phenotype related to defects in methyl-directed mismatch repair (MR) genes. We investigated whether there was a direct link between the mutator phenotype and virulence by (i) studying the relationships between mutation rate and virulence in a mouse model of extraintestinal virulence for 88 com...
متن کاملSpontaneously arising mutL mutators in evolving Escherichia coli populations are the result of changes in repeat length.
Over the course of thousands of generations of growth in a glucose-limited environment, 3 of 12 experimental populations of Escherichia coli spontaneously and independently evolved greatly increased mutation rates. In two of the populations, the mutations responsible for this increased mutation rate lie in the same region of the mismatch repair gene mutL. In this region, a 6-bp repeat is presen...
متن کاملIs efficiency of suppressor tRNAs controlled at the level of ribosomal proofreading in vivo?
Ribosomal rpsD mutations did not stimulate nonsense suppressor tRNAs in a general manner according to their increased ribosomal ambiguity and decreased proofreading efficiency. Streptomycin, which stimulates error production by blocking proofreading in vitro, did not increase efficiency of suppressor tRNAs in strains with normal or streptomycin-resistant (rpsL) ribosomes. It did so only in comb...
